[Updated at 1:51 p.m. ET] This live blog is wrapping up, but please check out our full story for the latest about today's document release.
[Updated at 1:48 p.m. ET] One of the warrants released Thursday cites an interview with a person who said that Lanza rarely left his home, that he was a shut-in, "and an avid gamer who plays Call of Duty, amongst other games." "Call of Duty" is a military-style war game.
In the house, according to the documents, were several books – one titled "NRA guide to the basics of pistol shooting," another about Asperger syndrome and one on autism. Both are developmental disorders that are not typically associated with violence.
Police also found a 2008 New York Times article about a shooting at Northern Illinois University. Police took from the house an NRA certificate for Nancy Lanza, a receipt for a shooting range in Oklahoma, a book titled "Train your brain to get happy," and three photographs "of what appears to be a deceased human covered with plastic and what appears to be blood."
As noted below, the NRA issued a statement today saying neither Lanza nor his mother were members.
[Updated at 1:45 p.m. ET] The main details of the shooting have long been known: The carnage began on the morning of December 14, when Lanza fatally shot his 52-year-old mother, Nancy Lanza, with a .22 caliber rifle.
But some of the details are new. "There was no indication of a struggle," according to a statement from Stephen J. Sedensky III, state's attorney for the judicial district of Danbury. The statement came with Thursday's release of five search warrants and related documents.
Lanza shot his mother in the forehead, one of the search warrants says.
Laden with weapons and ammunition, Lanza then went to the elementary school, shooting his way into the building where he killed the 26 victims with a Bushmaster .223 caliber model XM15 rifle, according to Sedensky.
The rampage ended when Lanza, using a Glock 10 mm handgun, shot himself.
Attached to the rifle police found a 30-round capacity magazine that still had 14 bullets Sedensky said, and a search of Lanza's body found that he was carrying more ammunition for the handguns as well as three more 30-round magazines for the Bushmaster, each fully loaded.
"Located in the area of the shootings were six additional 30-round magazines," Sedensky said in his statement, three of them empty and the others holding 10, 11, and 13 rounds. Police found 154 spent .223 caliber casings at the school.
All of the guns appear to have been bought by Lanza's mother, the state's attorney said.
[Updated at 12:59 p.m. ET] We've gotten all the documents together in one place. Here are the documents that Connecticut prosecutors released today in the Newtown investigation.
[Updated at 12:35 p.m. ET] Back to today's Newtown document release. The National Rifle Association has issued a statement, apparently reacting to what the papers say about investigators finding NRA certificates for Lanza and his mother, Nancy.
"There is no record of a member relationship between Newtown killer Adam Lanza, nor between Nancy Lanza, A. Lanza or N. Lanza with the National Rifle Association," the NRA statement said. "Reporting to the contrary is reckless, false and defamatory."

[Updated at 1:20 p.m.] "I'm very optimistic that DOMA will be struck down, it has no rational basis for being," House Minority Leader Nancy Pelosi said just now. Pelosi was at the Supreme Court to hear arguments over DOMA and California's Proposition 8 over the past two days.
Pelosi's district has been at the epicenter of gay rights for decades. She called the oral arguments at the Supreme Court "thrilling."
[Updated at 12:48 p.m. ET] We're signing off on this end for now - check out our main story for more detail and analysis as it comes today. We answer your questions here, and want to hear from you here.
Don't forget to join us again here tomorrow, when the Supreme Court hears the second round of debate on same-sex marriage: the Defense of Marriage Act.
[Updated at 12:31 p.m. ET] Director Rob Reiner, who watched today’s oral arguments, is a vocal critic against Proposition 8. Here's what he had to say after court adjourned:
“Today is a historic day for all those who believe in freedom and equality. After more than four years of working our case through victories at the federal District and Circuit courts, we finally had an opportunity today to present our arguments in support of marriage equality for gay and lesbian Americans before the highest court in the land. This case has always been about the love shared by two individuals and about the central promise from our nation’s founding that all men are created equal and are endowed with inalienable rights, including the pursuit of happiness.
[Updated at 12:11 p.m. ET] Andrew Pugno, general counsel for ProtectMarriage.com, tells reporters outside the court that he believes both sides of the argument have agreed that it is impossible to know with certainly how society would change by redefining "a fundamental institution such as marriage.
[Updated at 12:04 p.m. ET] “Today we feel we clearly presented the winning case for marriage,” says Andrew Pugno, general counsel for ProtectMarriage.com, who is speaking with reporters now.
[Updated at 12:01 p.m. ET] Charles Cooper, lead counsel defending Proposition 8, told reporters that he couldn't sum up his argument in a couple of sentences. "We believe Proposition 8 is constitutional," he said, making a brief statement.
[Updated at 11:48 a.m. ET] Kris Perry, a plaintiff in the Prop 8 case, just spoke, saying: "In this country as children, we learn that there's a founding principle, that all men and women are created equal. … Unfortunately with the passage of Proposition 8, we learned that there are group of people in California who are not being treated equally."
"We look forward to a day when prop 8 is officially eliminated and equality is restored to the state of California."
[Updated at 11:45 a.m. ET] Republican Ted Olson and Democrat David Boies, who joined forces to argue against Prop 8, are speaking outside the courthouse now. What's important from today, Olson said, is "the American people were listening to the argument. The other side, nobody really offered a defense."
"We're very gratified they listened, they heard, they asked hard questions, (but) there is no denying where the right is, and we hope the court (rules that way) in June."
[Updated at 11:43 a.m. ET] According to Toobin, there were a lot of questions along these lines from Justices Scalia and Alito: We don’t know the effects of same sex parenting on children, so why don’t we wait and let the states go experiment? Why do we, the Supreme Court, have to get involved in this process?
Toobin said Roberts also seemed sympathetic to these questions.
[Updated at 11:39 a.m. ET] The attorney general and the governor of California have refused to defend Prop 8. So the question, Toobin says, is "Who can defend the law? Who has the standing?" The answer to that question will be key to resolving the case.
Conservative Justices Scalia, Alito and Roberts were "very hostile of idea of the court imposing same sex marriage," according to Toobin. The four Democratic justices seemed favorably disposed.
Justice Kennedy seemed like he was in the middle, he said things that would "give comfort for both sides," Toobin says. Kennedy suggested the issue was brought prematurely before the court.
[Updated at 11:37 a.m. ET] The justices seemed very focused on how Prop 8 affects children, with Justice Kagan at some point suggesting that California have a law allowing same-sex marriage for people past child-bearing age, Toobin said.
Kagan said, according to Toobin: “I assure you if two 55 year old people, there aren’t a lot of children (coming from that marriage).”
[Updated at 11:34 a.m. ET] "This was a deeply divided Supreme Court, a court that seemed groping for answers," CNN senior legal analyst Jeffrey Toobin said after watching the arguments. "Now I think its even harder to predict the result of this case after hearing this argument."
[Updated at 11:31 a.m. ET] Oral arguments have wrapped up, according to CNN Supreme Court producer Bill Mears. They went just a bit over schedule, lasting about one hour and 20 minutes.
[Updated at 11:23 a.m. ET] While we wait on word from the courthouse, consider this: A new CNN/ORC International Poll indicates that 53% of Americans support same-sex marriage. In the same survey, 57% of respondents said they had a family member or close friend who is gay or lesbian.
Here's a look at the issue, by the numbers.
[Updated at 11:06 a.m. ET] The same-sex marriage debate is a huge issue, and the lawyers inside were penciled in for an hour to make their cases. Doesn't sound like much time, but to be fair, the oral arguments regarding the Affordable Care Act (aka "Obamacare") last March lasted roughly two hours.
Tomorrow's DOMA arguments have been given one hour and 50 minutes. We'll see if they stay on schedule today.
[Updated at 10:46 a.m. ET] If all is going to plan, Jean Podrasky, a lesbian whose first cousin happens to be Chief Justice John Roberts, is inside the court hearing the arguments.
"I know that my cousin is a good man," she wrote in an op-ed this week. "I feel confident that John is wise enough to see that society is becoming more accepting of the humanity of same-sex couples and the simple truth that we deserve to be treated with dignity, respect, and equality under the law."
You might see a lot of red avatars with a “=” equal sign in your Twitter feed today. Supporters of marriage rights for same-sex couples are wearing red today to show their support – both on their persons and their social media accounts. That includes Maryland Gov. Martin O’Malley.
A Nigerian militant group on Saturday announced the deaths of seven workers from a construction company who had been taken hostage last month.
The group, Ansar al-Muslimeen (widely known as Ansaru), released video stills of some of the bodies and blamed the deaths on a joint Nigerian-British military operation intended to free the hostages. There was no immediate word from those governments.
The militants on February 18 claimed responsibility for the kidnappings of the seven construction workers taken from their office in northeastern Nigeria.FULL STORY
