Wallace: Wonders of nature have been solace of my life

Alfred Russel Wallace discovered natural selection independently of Charles Darwin. Through his letters, available online for the first time, he tells us of his research, expeditions and enduring fascination for nature's mysteries.

You are famously joint author, with Darwin, of the first paper describing the origin of species and natural selection, published in 1858. When did you first get the idea?
I begin [in 1847] to feel rather dissatisfied with a mere local collection – little is to be learnt by it. I sh[ould]d like to take some one family, to study thoroughly – principally with a view to the theory of the origin of species. By that means I am strongly of [the] opinion that some definite results might be arrived at.

This desire led you to Brazil to collect birds, butterflies and beetles to try to discover what drives the evolution of new species. Were there any incidents on the voyage?
On Friday the 6th of August [1852]… the Captain (who was the owner of the vessel) came into the cabin & said "I am afraid the ship's on fire. Come & see what you think of it."

Despite that harrowing experience, you next undertook an 8 year expedition to the Malay Archipelago, where you discovered the invisible boundary between the animals of Asia and the Australian region, which would later be called the Wallace Line in your honour. What fascinated you most on that trip?
The Birds have however interested me much more than the insects, they are proportionally much more numerous, and throw great light on the laws of Geographical distribution of Animals in the East… As an instance I may mention the Cockatoos, a group of birds confined to Australia & the Moluccas, but quite unknown in Java Borneo Sumatra & Malacca… Many other species illustrate the same fact.

You have been famously good-natured about sharing the discovery of natural selection with Darwin…
I also look upon it as a most fortunate circumstance that I had a short time ago commenced a correspondence with Mr. Darwin on the subject of "Varieties", since it has led to the earlier publication of a portion of his researches & has secured to him a claim to priority which an independent publication either by myself or some other party might have injuriously effected

What did you and Darwin have in common?
In early life both Darwin and myself became ardent beetle-hunters. Both Darwin and myself had, what he terms "the mere passion of collecting"… Now it is this superficial and almost child-like interest in the outward forms of living things, which, though often despised as unscientific, happened to be the only one which would lead us towards a solution of the problem of species.

Do you feel your contribution has been overlooked?
The idea came to me, as it had come to Darwin, in a sudden flash of insight: it was thought out in a few hours – was written down with such a sketch of its various applications and developments… then copied on thin letter-paper and sent off to Darwin – all within one week.

I should have had no cause for complaint if the respective shares of Darwin and myself in regard to the elucidation of nature's method of organic development had been thenceforth estimated as being, roughly, proportional to the time we had each bestowed upon it when it was thus first given to the world – that is to say, as 20 years is to one week.

You helped Darwin with the puzzle of bright colouration in animals, which led to the concept of warning colours. To ask his question again, why are some caterpillars so brightly coloured?
[Since some]… are protected by a disagreeable taste or odour, it would be a positive advantage to them never to be mistaken for any of the palatable caterpillars… Any gaudy & conspicuous colour therefore, that would plainly distinguish them from the brown & green eatable caterpillars, would enable birds to recognise them easily as a kind not fit for food, & thus they would escape seizure which is as bad as being eaten.

How did you feel looking back on your life's work, at the age of 89?
The wonders of nature have been the delight and solace of… life. Nature has afforded… an ever increasing rapture, and the attempt to solve some of her myriad problems an ever-growing sense of mystery and awe.

Do you have a message for our readers?
I sincerely wish you all some of the delight in the mere contemplation of nature's mysteries and beauties which I have enjoyed.

More covered linkways, elderly friendly bridges for commuters

SINGAPORE: The government will spend close to S$700 million to make transport nodes more accessible, elderly friendly and conducive for commuters.

The plans, mapped out in the new Land Transport Master Plan, were announced by Transport Minister Lui Tuck Yew on Wednesday.

One of the new initiatives -- Walk2Ride -- will make it easier for more commuters to walk to MRT stations.

The Land Transport Authority (LTA) will build sheltered linkways within a 400-metre radius from all existing MRT stations, compared to the current radius of 200 metres.

LTA will also link up developments within a 200-metre radius of all bus interchanges, LRT stations and high-usage bus shelters.

In all, some 200 kilometres of linkways will be added islandwide by 2018, more than four times the existing 46 kilometres today.

The project is expected to cost some S$330 million and will begin from 2014.

Currently, sheltered linkways are built to link only to schools, healthcare institutions and other transport nodes like bus stops and taxi stands.

But under Walk2Ride, shopping, leisure, commercial and residential areas will also be linked.

LTA intends to leverage on existing linkways and work with the different town councils before deciding on which areas will be given priority.

The Walk2Ride initiative is being rolled out, following a successful trial at Lakeside MRT.

More pedestrian overhead bridges will also become more elderly and wheel-chair friendly.

LTA has reviewed the provision criteria to build more lifts at such bridges. These include those located within 200 metres of MRT stations and 100 metres of LRT stations.

Some 40 bridges have been identified for further feasibility studies.

A budget of about S$60 million has been set aside to install the lifts from 2014. Half of them will be completed by 2016 and the remaining by 2018.

Another S$300 million will be spent on installing some 20 kilometres of noise barriers along elevated MRT tracks.

Since September, LTA has been measuring noise levels at 455 residential flats located close to such tracks.

In some locations, the noise levels were found to have exceeded the National Environment Agency's guideline of 67 decibels.

Mr Lui said residents living close to MRT viaducts, such as those in Simei, Marsiling and Dover, can expect noise levels to be reduced by about five to 10 decibels.

LTA intends to start installing the barriers from end of this year and complete them by 2020.

Deformed Dolphin Accepted Into New Family

In 2011, behavioral ecologists Alexander Wilson and Jens Krause of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Germany were surprised to discover that a group of sperm whales (Physeter macrocephalus)—animals not usually known for forging bonds with other species—had taken in an adult bottlenose dolphin (Tursiops truncatus).

The researchers observed the group in the ocean surrounding the Azores (map)—about 1,000 miles (1,600 kilometers) off the coast of Lisbon, Portugal—for eight days as the dolphin traveled, foraged, and played with both the adult whales and their calves. When the dolphin rubbed its body against the whales, they would sometimes return the gesture.

Among terrestrial animals, cross-species interactions are not uncommon. These mostly temporary alliances are forged for foraging benefits and protection against predators, said Wilson.

They could also be satisfying a desire for the company of other animals, added marine biologist John Francis, vice president for research, conservation, and exploration at the National Geographic Society (the Society owns National Geographic news).

Photographs of dogs nursing tiger cubs, stories of a signing gorilla adopting a pet cat, and videos of a leopard caring for a baby baboon have long circulated the web and caught national attention.

A Rare Alliance

And although dolphins are known for being sociable animals, Wilson called the alliance between sperm whale and bottlenose dolphin rare, as it has never, to his knowledge, been witnessed before.

This association may have started with something called bow riding, a common behavior among dolphins during which they ride the pressure waves generated by the bow of a ship or, in this case, whales, suggested Francis.

"Hanging around slower creatures to catch a ride might have been the first advantage [of such behavior]," he said, adding that this may have also started out as simply a playful encounter.

Wilson suggested that the dolphin's peculiar spinal shape made it more likely to initiate an interaction with the large and slow-moving whales. "Perhaps it could not keep up with or was picked on by other members of its dolphin group," he said in an email.

Default

But the "million-dollar question," as Wilson puts it, is why the whales accepted the lone dolphin. Among several theories presented in an upcoming paper in Aquatic Mammals describing the scientists' observations, they propose that the dolphin may have been regarded as nonthreatening and that it was accepted by default because of the way adult sperm whales "babysit" their calves.

Sperm whales alternate their dives between group members, always leaving one adult near the surface to watch the juveniles. "What is likely is that the presence of the calves—which cannot dive very deep or for very long—allowed the dolphin to maintain contact with the group," Wilson said.

Wilson doesn't believe the dolphin approached the sperm whales for help in protecting itself from predators, since there aren't many dolphin predators in the waters surrounding the Azores.

But Francis was not so quick to discount the idea. "I don't buy that there is no predator in the lifelong experience of the whales and dolphins frequenting the Azores," he said.

He suggested that it could be just as possible that the sperm whales accepted the dolphin for added protection against their own predators, like the killer whale (Orcinus orca), while traveling. "They see killer whales off the Azores, and while they may not be around regularly, it does not take a lot of encounters to make [other] whales defensive," he said.

Clinton on Benghazi: Afghanistan Diverted Resources

House Republicans slammed Secretary of State Hillary Clinton today for her lack of awareness of State Department cables warning of security threats in Benghazi, Libya, prior to the Sept. 11 attack that killed four Americans, including Amb. Chris Stevens.

In the second congressional hearing of the day reviewing a report by the Accountability Review Board on the State Department's security failures, Rep. Michael McCaul, R-Texas, asked Clinton this afternoon why her office had not responded to a notification from Stevens about potential dangers in Libya.

"Congressman, that cable did not come to my attention," Clinton calmly told the House Foreign Affairs Committee hours after her Senate testimony this morning. "I'm not aware of anyone within my office, within the secretary's office having seen that cable."

She added that "1.43 million cables come to my office. They're all addressed to me."

Hillary Clinton's Fiery Moment at Benghazi Hearing

Rep. Matt Salmon, R-Ariz., asked Clinton whether she thought that signaled the need for a shifting of priorities to make sure she is notified about these kinds of threats in the future.

"That's exactly what I'm intent on doing," Clinton said. "We have work to do. We have work to do inside the department. We have work to do with our partners in DOD and the intelligence community."

Such answers failed to appease members like Rep. Jeff Duncan, R-S.C., who accused Clinton of letting "the consulate become a death trap."

Clinton also told the House committee that an emphasis on security in Iraq and Afghanistan in the past decade diverted resources from other outposts around the world.

She told Rep. Chris Smith, R-N.J., that legislation he championed reorganizing the State Department in the 19990s had "been very important in protecting our people around the world," but that the need for funding was ongoing and unmet.

Clinton reprised her role as defender of the State Department this afternoon in the second half of congressional testimony on the security failures that led to the deaths of Stevens and the other Americans.

Stevens understood the significance of the mission, she told the committee several hours after a morning Senate appearance.

"That's why Chris Stevens went to Benghazi in the first place," she said. "Nobody knew the dangers better than Chris, first during the revolution and then during the transition. A weak Libyan government, marauding militias, even terrorist groups … a bomb exploded in the parking lot of his hotel. He never wavered. He never asked to come home. He never said let's shut it down, quit, go somewhere else."

Representatives repeatedly asked about U.N. Ambassador Susan Rice's assertion on Sunday morning talk shows in September that the attack was fueled by outrage over a video attacking Islam.

Clinton's response was to refer to the ARB report, which said the motivations behind the attack were complicated and still not all known. She maintained that Rice was speaking based upon talking points given to her by the intelligence community.

Rep. Joe Wilson, R-S.C., asked why the secretary of state herself did not appear in Rice's place to give those televised explanations to the country.

"Well, I have to confess here in public [that] going on the Sunday shows is not my favorite thing to do. There are other things that I prefer to do on Sunday mornings," Clinton replied. "And I did feel strongly that we had a lot that we had to manage, that I had to respond to. And I thought that should be my priority."

The afternoon appearance followed morning testimony from an energized Clinton, who stood her ground and told the Senate Foreign Relations Committee that she has overseen plans to secure diplomatic outposts around the world while cuts in State Department funding undermine those efforts.

Citing a report by the department's Accountability Review Board on the security failures that led to the deaths of four Americans in Benghazi, Libya, during an attack last year, Clinton said the board is pushing for an increase in funding to facilities of more than $2 billion per year.

"Consistent shortfalls have required the department to prioritize available funding out of security accounts," Clinton told the Senate this morning, while again taking responsibility for the Benghazi attack. "And I will be the first to say that the prioritization process was at times imperfect, but as the ARB said, the funds provided were inadequate. So we need to work together to overcome that."

Clinton, showing little effect from her recent illnesses, choked up earlier in discussing the Benghazi attack.

"I stood next to President Obama as the Marines carried those flag-draped caskets off the plane at Andrews," Clinton said this morning, her voice growing hoarse with emotion. "I put my arms around the mothers and fathers, sisters and brothers, sons and daughters."

The outgoing secretary of state was the only witness to giving long-awaited testimony before the Foreign Relations Committee this morning, and appeared before the House Foreign Affairs Committee at 2 p.m.

The secretary, who postponed her testimony in December, started today by giving context to the terrorist attack.

"Any clear-eyed examination of this matter must begin with this sobering fact," Clinton began. "Since 1988, there have been 19 Accountability Review Boards investigating attacks on American diplomats and their facilities."

But the secretary did not deny her role in the failures, saying that as secretary of state, she has "no higher priority and no greater responsibility" than protecting American diplomats abroad like those killed in Benghazi.

"As I have said many times, I take responsibility, and nobody is more committed to getting this right," Clinton said. "I am determined to leave the State Department and our country safer, stronger and more secure."

Among the steps Clinton has taken, she said, is to "elevate the discussion and the decision-making to make sure there's not any" suggestions that get missed, as there were in this case.

Clinton testified that the United States needs to be able to "chew gum and walk at the same time," working to shore up its fiscal situation while also strengthening security, and she refuted the idea that across-the-board cuts slated to take place in March, commonly referred to as sequestration, were the way to do that.

"Now sequestration will be very damaging to the State Department and USAID if it does come to pass, because it throws the baby out with the bath," Clinton said, referring to the United States Agency for International Development, which administers civilian foreign aid.

While the State Department does need to make cuts in certain areas, "there are also a lot of very essential programs … that we can't afford to cut more of," she added.

More than four months have passed since the attack killed U.S. Ambassador Christopher Stevens and three other Americans in Libya. These meetings, during which Clinton discussed the report on State Department security failures by the Accountability Review Board, were postponed because of her recent illness.

Clinton told the Senate that the State Department is on track to have 85 percent of action items based on the recommendations in the ARB report accomplished by March, with some already implemented.

MIT website hacked in tribute to Aaron Swartz

Hal Hodson, technology reporter

A tribute to internet activist Aaron Swartz replaced the homepage for the Massachusetts Institute of Technology today, in an apparent act of protest over the university's role in the legal case that led up to Swartz's suicide on 11 Jan.

For a short time, visitors to the MIT.edu home page found a message that read: "R.I.P. Aaron Swartz. Hacked by grand wizard of Lulzsec, Sabu. God Bless America. Down With Anonymous." The background was watermarked with words from a blog post, written by Swartz, titled "Immoral".

Attributing the defacement to "grand wizard of Lulzsec, Sabu" lent the page a sarcastic air, as it's widely known that the former Lulzsec leader was outed as an FBI informant last year.

The attack on MIT's website came amid widespread criticism of how the university handled the case against Swartz, including an article in The New York Times that quoted Swartz's father as saying: "We don't believe [MIT] acted in a neutral way. My belief is they put their institutional concerns first."

According to MIT's service status page, network service was restored within the university as of 1:30 pm EST. The university had not yet returned New Scientist's request for comment when this story was published.

This is the second time since Swartz' death that the MIT site has been the target of attacks. Previously, an MIT sub-domain was replaced with a manifesto for reform of computer and copyright laws. The authors claimed to be operating as a part of the online activist group, Anonymous.

British PM to offer "in-or-out" referendum on EU

LONDON: Prime Minister David Cameron will on Wednesday propose holding a referendum after 2015 giving British people the choice of staying in or leaving the European Union.

Cameron will say in a long-awaited speech in London that he wants to renegotiate the terms of Britain's membership because "public disillusionment with the EU is at an all-time high", and then put the new terms to the people.

According to pre-released excerpts, Cameron will say his Conservative party will make the pledge in its campaign for the general election scheduled to take place in two years' time.

"The next Conservative manifesto in 2015 will ask for a mandate from the British people for a Conservative government to negotiate a new settlement with our European partners in the next parliament," the speech says.

"And when we have negotiated that new settlement, we will give the British people a referendum with a very simple in-or-out choice to stay in the EU on these new terms, or come out altogether. It will be an in-out referendum."

If a Conservative government wins outright victory, a referendum would be held in the first half of the next parliament, he adds.

Cameron will say he believes a referendum on British membership of the 27-nation bloc is necessary because in its current form the EU is intruding into British life.

"People feel the EU is heading in a direction they never signed up to. They resent the interference in our national life by what they see as unnecessary rules and regulation. And they wonder what the point of it all is," he will say.

Cameron had been due to give the speech in Amsterdam last Friday but postponed it because of the Algeria gas plant hostage crisis.

In the re-scheduled speech, Cameron says he understands the "impatience" of those who want to hold a referendum immediately, but insists the time is not right.

"I don't believe that to make a decision at this moment is the right way forward, either for Britain or for Europe as a whole," it says.

"A vote today between the status quo and leaving would be an entirely false choice."

Explaining why he wants to wait, Cameron will say the eurozone crisis will leave the EU transformed "perhaps beyond recognition" and that Britain wants to help shape the future of the bloc that emerges from it.

Cameron has faced pressure from the eurosceptic rightwing of the Conservative Party to take a stand on Europe, an issue that has long divided the party.

But his insistence on holding a referendum with a stark in-or-out choice will anger many of Britain's fellow EU member states, as well as his coalition government partners, the pro-Europe Liberal Democrats.

It will also dismay many business leaders and the opposition Labour party, who have warned Cameron that to offer the possibility of a referendum risks creating uncertainty and will lead Britain to the edge of an "economic cliff".

Cameron has also faced warnings from Britain's close ally the United States against isolating the country from the EU.

The speech has been delayed a number of times.

Plans to give it first emerged six months ago, and there was talk that Cameron might deliver it at the Conservative party's annual conference in October, followed by reports that he would give it at Christmas.

The speech was then widely expected on January 22, but Cameron moved it forward when it emerged that it clashed with commemorations for the 50th anniversary of Franco-German reconciliation following World War II.

Then the Algeria crisis intervened to force another change of plans.

Elder Scrolls Online trailer, beta electrify the imagination

Will The Elder Scrolls Online recapture MMORPG gamers?

(Credit:
Screenshot by Christopher MacManus/CNET)

Developer Zenimax Online Studios wowed the gaming community today with a six-minute explosive cinematic trailer showing some heart-racing action in the grandiose world of Tamriel, the primary location of the upcoming The Elder Scrolls Online. Be sure to play the CGI trailer in high-definition and at full screen for maximum pleasure.

To add further excitement to the reveal, Zenimax also opened the doors to Elder Scrolls Online beta registrations today, giving anyone the chance to get in on the action. Of course, to get in, you'll need to submit answers to an array of personal questions (name, birthday, and so on) and submit full system diagnostic information. Zenimax also requires that you answer questions about any other relevant MMORPGs you've played; your play style (solo, group, etc.); preferred activities in MMORPGs; and previous stints as a beta tester.

If that wasn't demanding enough, you then have to tell the developer why you should be chosen as a beta tester. Amusingly, a progress bar hangs over the Web page and indicates your chance rating at even being selected at all -- fortunately, I scored an above-average, so I assume experience matters.

Zenimax and publisher Bethesda Softworks didn't disclose when The Elder Scrolls Online would begin beta testing, or reveal much information other than the fact that PC and
Mac gamers can participate. Read the beta FAQ for more details, or listen to the latest Bethesda podcast featuring developers answering some more questions about the upcoming experience.

The Promise and Perils of Mining Asteroids

Encouraged by new space technologies, a growing fleet of commercial rockets and the vast potential to generate riches, a group of entrepreneurs announced Tuesday that they planned to mine the thousands of near-Earth asteroids in the coming decades.

The new company, Deep Space Industries (DSI), is not the first in the field, nor is it the most well-financed. But with their ambition to become the first asteroid prospectors, and ultimately miners and manufacturers, they are aggressively going after what Mark Sonter, a member of DSI's board of directors, called "the main resource opportunity of the 21st century." (Related: "Asteroid Hunter to Be First Private Deep-Space Mission?")

Prospecting using miniaturized "cubesat" probes the size of a laptop will begin by 2015, company executives announced. They plan to return collections of asteroid samples to Earth not long after.

"Using low cost technologies, and combining the legacy of [the United States'] space program with the innovation of today's young high tech geniuses, we will do things that would have been impossible just a few years ago," said Rick Tumlinson, company chairman and a longtime visionary and organizer in the world of commercial space [not sure what commercial space means].

"We sit in a sea of resources so infinite they're impossible to describe," Tumlinson said.

Added Value

There are some 9,000 asteroids described as "near-Earth," and they contain several classes of resources that entrepreneurs are now eyeing as economically valuable.

Elements such as gold and platinum can be found on some asteroids. But water, silicon, nickel, and iron are the elements expected to become central to a space "economy" should it ever develop.

Water can be "mined" for its hydrogen (a fuel) and oxygen (needed for humans in space), while silicon can be used for solar power systems, and the ubiquitous nickel and iron for potential space manufacturing. (See an interactive on asteroid mining.)

Sonter, an Australian mining consultant and asteroid specialist, said that 700 to 800 near-Earth asteroids are easier to reach and land on than the moon.

DSI's prospecting spacecraft will be called "FireFlies," a reference to the popular science fiction television series of the same name. The FireFlies will hitchhike on rockets carrying up communication satellites or scientific instruments, but they will be designed so that they also have their own propulsion systems. The larger mining spacecraft to follow have been named "DragonFlies."

Efficiencies

It all sounds like science fiction, but CEO David Gump said that the technology is evolving so quickly that a space economy can soon become a reality. Providing resources from beyond Earth to power spacecraft and keep space travelers alive is the logical way to go.

That's because the most expensive and resource-intensive aspect of space travel is pushing through the Earth's atmosphere. Some 90 percent of the weight lifted by a rocket sending a capsule to Mars is fuel. Speaking during a press conference at the Santa Monica Museum of Flying in California, Gump said that Mars exploration would be much cheaper, and more efficient, if some of the fuel could be picked up en route. (Related: "7 Ways You Could Blast Off by 2023.")

Although there is little competition in the asteroid mining field so far, DSI has some large hurdles ahead of it. The first company to announce plans for asteroid mining was Planetary Resources, Inc. in spring 2012—the group is backed by big-name investors such as Google's Larry Page and Eric Schmidt, filmmaker James Cameron, and early Google investor Ram Shriram. DSI is still looking for funding.

Owning Asteroids

While these potential space entrepreneurs are confident they can physically lay claim to resources beyond Earth, there remain untested legal issues.

The United Nations Space Treaty of 1967 expressly forbids ownership of other celestial bodies by governments on Earth. But American administrations have long argued that the same is not true of private companies and potential mining rights.

While an American court has ruled that an individual cannot own an asteroid—as in the case of Gregory Nemitz, who laid claim to 433 Eros as a NASA spacecraft was approaching it in 2001—the question of extraction rights has not been tested.

Moon rocks brought back to Earth during the Apollo program are considered to belong to the United States, and the Russian space agency has sold some moon samples it has returned to Earth-sales seen by some as setting a precedent.

Despite the potential for future legal issues, DSI's Gump said his group recently met with top NASA officials to discuss issues regarding technology and capital, and came away optimistic. "There's a great hunger for the idea of getting space missions done with smaller, cheaper 'cubesat' technology and for increased private sector involvement."

Everyone involved acknowledged the vast challenges and risks ahead, but they see an equally vast potential—both financial and societal.

"Over the decades, we believe these efforts will help expand the civilization of Earth into the cosmos, and change what it means to be a citizen of this planet," Tumlinson said.

Teen Planned to Attack Walmart After Killing Family

The New Mexico teenager who used an assault rifle to kill his mother, father and younger siblings told police he hoped to shoot up a Walmart after the family rampage and cause "mass destruction."

Police said they are also considering charging the shooter's 12-year-old girlfriend.

According to new information released by police today, Nehemiah Griego, the 15-year-old son of an Albuquerque pastor, had plans to kill his family, his girlfriend's family, and local Walmart shoppers for weeks before he acted on the impulse on Sunday.

"Nehemiah said after killing five of his family members he reloaded the weapons so that he could drive to a populated area to murder more people," a police report from the incident stated.

"Nehemiah stated he wanted to shoot people at random and eventually be killed while exchanging gunfire with law enforcement," the report said.

The shooting spree began shortly around 1 a.m. on Sunday, when Griego snuck into his parents' bedroom while his mother, Sara Griego, was asleep. There he raided the closet where the family kept their guns, and immediately used a .22 rifle to kill her, according to the Bernalillo County Sheriff's Department.

Griego's 9-year-old brother was sleeping with his mother at the time and woke up. When Griego told the boy his mother was dead, the youngster didn't believe him, according to a police report.

"So Nehemiah picked up his mother's head to show his brother her bloody face," the report states. "Nehemiah stated his brother became so upset so he shot his brother in the head."

He then went into his sisters' bedroom. "Nehemiah stated when he entered he noticed that his sisters were crying and he shot them in the head," the police report states. The girls were 5 and 2 years old.

The teenager waited for his father to come from his overnight shift working at a nearby rescue mission. When his father, Greg Griego, walked into the home around 5 a.m., unaware of what had taken place, Griego shot him multiple times with the AR-15 rifle, Sheriff Dan Houston said today.

Greg Griego was a former church pastor at Calvary Church in Albuquerque, and worked as a chaplain at a local jail where he counseled convicts. The family was very involved in the church, according to its website.

The complaint said Griego took a photo of his dead mother and "sent it to his girlfriend."

Griego then packed up the guns, including two shotguns, as well as ammunition for the rifles, and planned to drive to a Walmart to shoot additional people.

Houston said today that Griego called his 12-year-old girlfriend Sunday and ended up spending the entire day with her rather than going to the Walmart. Around 8 p.m. on Sunday, the pair drove to Calvary Church, and Griego said his family had died in a car crash. Someone on the church's staff then called 911, Houston said.

"At this time, Nehemiah had been contemplating this for some time. The information that Nehemiah had contemplated going to the local Walmart and participating in a shooting in there is accurate," Houston said. "There is no information at all that he went to church to cause anyone bodily harm there. The suspect also contemplated killing his girlfriend's parents."

The girlfriend's name was not released, but police are investigating whether to press any charges against her, Houston said. Houston said she had some knowledge about the deaths during the day Sunday.

Griego told cops he sent a picture of his dead mother to his girlfriend after the murder.

Sheriff's deputies were dispatched to the Griego home around 9:15 p.m. on Sunday and arrived 10 minutes later, where they found the five bodies.

Griego lied to investigators about the attack, telling them he came home around 5 a.m. that morning and found his family dead. He said he then took the guns to protect himself.

Griego quickly admitted to the crime when pressed by police, telling investigators he was "frustrated" with his mother. Deputies said he was "unemotional" and "very stern" during the confession.
