Investigators are putting together a timeline of Friday's shooting, beginning with Adam Lanza's allegedly shooting his mother while she slept before driving to Sandy Hook Elementary School. NBC's Pete Williams reports.
Updated at 7:34 p.m. ET: Adam Lanza, who authorities say killed 20 children and six women in Connecticut, shot his mother in the head multiple times before heading to Sandy Hook Elementary School, where he fired hundreds of rounds and died with hundreds more at his disposal, police said Sunday.
It was an extraordinary amount of weaponry that Connecticut State Police Lt. Paul Vance described Sunday. In addition to an assault-style rifle and at least two handguns, he also had a shotgun in reserve in the car he drove to the school.
And when he was found, Lanza, 20, still had "hundreds of rounds" of ammunition in multiple magazines, after having already fired hundreds of rounds inside the school, where he killed himself with a gunshot to the head as emergency crews arrived Friday.
An explanation still hasn't emerged for why Lanza killed the 26 people at Sandy Hook, but Connecticut Gov. Dan Malloy opened a window for speculation when he told NBC News on Sunday that it appeared that Lanza attended the school as a youngster. Earlier reports that his mother, Nancy, may have taught there haven't borne out.
"He attended there — that's what I'm led to believe," Malloy said on NBC's "Meet the Press."
The children — 12 girls and eight boys, all of them 6 or 7 years old — were shot as many as 11 times, H. Wayne Carver, the state medical examiner, said Saturday. It appeared that Lanza had enough weapons and ammunition with him to have killed many, many more.
Police were analyzing the weaponry, along with a computer they found at the Lanzas' home, for possible leads on the gunman's motive, NBC News' Pete Williams reported.
Conn. shooting suspect Adam Lanza's father: 'We too are asking why'
Lanza's parents were divorced, and he lived with his mother, who home-schooled him for part of his childhood, Malloy said.
Connecticut school shooter was 'very nervous around people'
"He had a very troubled life," Malloy said. "He never seemed to be a good fit. ... It was a very difficult time for him and his mother."
Malloy declined to answer whether any documented evidence had been uncovered that Lanza might have been mentally disturbed. At Western Connecticut State University in Danbury, where he enrolled at about 16 in 2008, there was never any indication of trouble, the university said in a statement Sunday.
Lanza took six classes — including website production, data modeling, Philosophy 101 and ethical theory — and compiled a solid 3.26 grade-point average.
Investigators resolutely refused to go into detail about the timing of events Friday during official briefings. But investigators told NBC News that Lanza first killed his mother, an avid gun enthusiast, with her own gun and then took multiple weapons with him as he drove to the school in her car.
To bypass security, Lanza smashed in a window, they said. He shot and killed Principal Dawn Hochsprung, 47, and Mary Sherlach, 56, a school psychologist, before proceeding to a classroom, where he found the door locked.
So he moved on to a second classroom, where he killed everyone he found, before doing the same in a third classroom, investigators believe. He then shot himself.

Although he was carrying three weapons, he used only one of them in all of the school killings — a Bushmaster .223-caliber assault-style rifle similar to the one used by the snipers who terrorized the Washington, D.C., area in 2002. It was purchased legally, they said. He used one of the handguns to kill himself.
Authorities haven't said how Nancy Lanza stored the weapons.
Marsha Lanza, Nancy Lanza's sister-in-law and Adam Lanza's aunt, said there was a good reason for a divorced woman who grew up with guns to have them in the house: self-defense.
"She lived alone. She was a female (who) lived alone," Marsha Lanza said.

If people could fly and afford one, they'd have a F-16 for "home defense". Nutbag mother produces nutbag son. Not a tough equation to figure out. It's unfortunate that innocent people had to be involved in their lunacy.

This Beyond Reason Act Came from Many Ideas ..in This man's Brain..
Where did The Ideas ..That led to this Act ..come from..WHAT Conditioned this Very Hurting ..Boy / man..?
I wish I owned a gun to protect myself from all of you crazy comment posters.
There really isn't much difference with these lone suicide attacks here in the USA and in those in the middle east that are called suicide bombers. Neither accomplishes anything except a personal vendetta or revenge. Ted Nugent must be proud of his NRA stance and his comments to take his guns to the streets if President Obama was re-elected. We should also remember the NRA supported candidate Romney.
It's amazing how many idiots something like this brings out ....to this forum.
There is no logical reason for this many guns to be floating around.
What will it take for this country to realize this?
It would take a completely new Congress with completely different rules on campaign fund contributions. If a person could not protect himself with a 6 shot 38 Caliber/357 and a shotgun then he/she is incapable of protecting themselves. The NRA and the gun store lobby have continued to allow manufacturer's to build bigger, heavier and wilder looking weapons since 1970. I came back from Vietnam that year and was shocked civilians could buy the same weapons we used as long as they were single shot. It is simply amazing what you can buy in a gun store these days. Too late now.
You have to wonder how many people in government are plotting schemes while the story of the shootings diverts public attention. just wondering..
Another paranoid gun owner heard from. I'm seeing a definite pattern here.
Was it his home schooling or his catholic schooling??
Leaving aside all the gun rhetoric for a moment:
I'm a teacher. Standard procedure for a "lock down" is to lock the door(s) your room. Why was this nutter able to get into the second classroom.
Back to the gun rhetoric: the NRA and its servants in public office have elevated the 2nd Amendment to the status of a secular religion. In the interest of public safety and for the good of our country, we passed the Patriot Act to curtail (not eliminate) some of our constitutional liberties. And we take off our shoes and ditch our shampoos at airports so we can avoid being blown out of the sky. It's a pain but it's worth it. Looks like gun control fits the same category.
Enough pious bafflegab equating a single woman with a house full of weapons with a "well ordered militia". If we can limit, regulate and license the number of dogs or cats a person crams in their home, we can limit and regulate weapons.
All this blather about how a single woman living alone needed guns for protection ignores the sad fact that she was shot in the head with her own guns. By someone she knew, and whom she knew to be a nutter.
"Marsha Lanza, Nancy Lanza's sister-in-law and Adam Lanza's aunt, said there was a good reason for a divorced woman who grew up with guns to have them in the house: self-defense. "She lived alone. She was a female (who) lived alone," Marsha Lanza said."
My father was a gun collector and enthusiast. I too grew up with guns. I'm female. I live alone.
No guns in my home!
While dad left the kid in the hands of the gun toting mother and found another wife.
Yep, it's daddy's fault. Of course you have no proof he didn't try to get custody but it fits in your little theory.
"So he moved on to a second classroom, where he killed everyone he found, before doing the same in a third classroom, investigators believe. He then shot himself."
A chilling, note perfect description of absolute horror. I hope the dead are at peace and the living can find peace in time.

Mystery
surrounds graves at boys' reform school
Marianna, Florida (CNN) -- This Florida panhandle town is the home of a mystery that has been lost to time.
A small cemetery buried deep into the grounds of a now-defunct boys reform school dates back to the early 1900s. Rusting white steel crosses mark the graves of 31 unidentified former students.
Former students said the deaths were at the hands of abusive administrators, but a 2009 state investigation determined there was no evidence of criminal activity connected with any of the deaths or of abusive treatment.
But the investigation did not clear up the mystery over the fate of 50 other students who died at the school and whose bodies have not been accounted for.
In the wake of that investigation, more former students -- who are now senior citizens -- have come forward with stories of abuse at the school, including alleged beatings, killings and the disappearance of students, during the 1940s, '50s and '60s.
Reform school guard, 85, denies beating boys
"These are children who came here and died, for one reason or another, and have just been lost in the woods," said Dr. Erin Kimmerle, an anthropologist from the University of South Florida who is leading a scientific search on the grounds of what used to be the Florida Industrial School for Boys
Using ground-penetrating radar, Kimmerle's team has located what she says appear to be 18 more remains than previously thought to have been buried there. After clearing the area, her team has determined that a total of 49 graves exist. All are unidentified.
"We found burials within the current marked cemetery, and then we found burials that extend beyond that," Kimmerle said.
Regarding the missing boys, "for the majority, there's no record of what happened to them. So, they may be buried here, they may have been shipped to their families. But we don't know," she said.
State and school records show that out of nearly 100 children who died while at the school, there are no burial records for 22 of them, according to Kimmerle.
"When there's no knowledge and no information, then people will speculate and rumors will persist or questions remain," she said.
Kimmerle, who worked on an international forensics team that amassed evidence used in war crimes trials from the conflicts in the former Yugoslavia, called the Florida project a humanitarian effort for the families of the former students and for the community.
"It's about restoring dignity," she said.
The team laid a grid using ground-penetrating radar to create a three-dimensional digital image of the area. They had to clear underbrush and trees when it became apparent the cemetery extended well beyond the small fenced area.
"We found numerous anomalies throughout," said Rich Estabrook, a public archaeologist working on the team. "Many of them tend to be in rows, and somewhat symmetrical."
The team believes these so-called "anomalies" are graves because they are lined up in east-west configurations, the traditional way Christians are buried. Exhumations will have to be requested by family members.
Adding to the mystery, Kimmerle's team has determined, based on reports from former workers and students, that another cemetery exists on the 1,400-acre property. Those graves could contain the bodies of black students, buried in a different area because of segregation.
The team has petitioned to search the area, and the Florida Department of Juvenile Justice has agreed to work with the researchers "on how best to provide them access to the site."
But they'll have to move quickly because the state is in the process of selling the entire property.

The Mich right to work law that was passed another attempt to destroy the middle class
Those guns sure protected her. What a clown. Either keep it hidden (only she should know where) or lock them up. Stupid mom. Dumb dumb dumb. I put part of the blame on her shoulders. She knew he was a mental case and then proceeds to take him shooting all of her high powered weapons.
Nice country we live in.
I think the mother bought guns initially to protect herself from intruders and then realized what a monster her son was. She might've been afraid of him especially when sleeping a night and probably had a gun under her pillow. She probably became a gun enthusiast in order to distract her from the harsh reality of taking care of her monster son. Even the monster's brother didn't have anything to do with him for 2 years. I hope the victims' families sue her estate and win. The fact that he was even able to get her guns, kill her, and then kill all these innocent people means that she's was at fault. She didn't take enough precautions.
STOP Stereo-Typing Sick Individuals.as "MONSTERS"..
Maybe His Mom..should have gotten Him Help..Because He Himself.....Could Not..
He killed 26 people and you're telling me he's not a MONSTER?? Are you kidding me? What about everywhere saying that EVIL visited Newtown on Friday? That's not EVil??
This entire country is sue crazy. You would sue a dead woman, killed by her own son, and blame her for the whole mess? You're crazier than the son.
Yes, I'm the blaming the dumb ass mother for letting her mentally ill son gain access to her arsenal of guns she was so proud of to kill 20 kids and 6 adults. Her estate will probably and hopefully be sued for damages and the victims' families will win and get the justice they deserve. If a gun owner is going to have guns carelessly lying around and a crime is committed, he or she will be held liable. The police, in their investigation, will probably make sure of that by gathering all the necessary evidence. All the mother's assets should be liquidated with the proceeds going to the victims. Gina is the crazy one for absolving the mother of any responsibility. Adam Lanza probably reminds her of her own son or a family member.
"STOP Stereo-Typing Sick Individuals.as "MONSTERS"..
Maybe His Mom..should have gotten Him Help..Because He Himself.....Could Not.."
Not all sick individuals are "MONSTERS"...Just the ones who kill, rape, maim etc. James Troutman, 24, was described by his fiancee as having Aspergers. He raped and strangled a neighbor, 9 year old Skylar Kauffman in Pennsylvania in 2011. Jonathan Holt, 24, sexually assaulted, shot and killed his neighbor Whitney Heichel, 21 in Oregon. He had a "meltdown the previous year.
I'm calling them as I see them: MONSTERS!
This is what we can expect with ABSENT dads, and loony moms. Everyone knew something was terribly wrong with this lunatic, and no family member did ANYTHING.
You can drop the "absent dads" BS. There is NO evidence that having a 'father' around makes any difference when you have a competent, caring mother and other strong family support . That's just more Religious RW rhetoric.
Everyone blames firearms for all of our nations massacres; however, no one seems to address the true reason... MENTAL ILLNESS. Ever since Jimmy Carter began the dismantling of our nation's Mental Health System, crime, suicide rates, homelessness, and massacres have escalated. Our jail and prison systems have become this nation's largest mental institution facilities.
Instead of our elected officials passing senseless gun control laws that do nothing to keep these horrible acts from occurring, lets call on our government to spend money and re-establish a national Mental Health system. Let's identify and treat people suffering from mental disorders before they can injure other people, whether it's a single family memeber or a school full of children. Examine all of the nations massacres and you will find that all of these perpetraters suffered from a serious mental heath disorder that was known at the time, but they never recieved proper professional attention and fell through the cracks. Whenever these massacres occur we all say "this is crazy," of course it is!!! because the people who commit such acts are "CRAZY!"
Jimmy Carter???????
Try Ronald Reagan, as Governor of California. Closed all the state mental facilities. Look it up.

"...a divorced woman who grew up with guns to have them in the house: self-defense.
"She lived alone. She was a female (who) lived alone," Marsha Lanza said."
Is that what the NRA told her? She needs a gun to protect her in a Conneticut suburb? What a civilized society! The Land of the Free and of the Brave. "Leader" of the "free" world. What a joke! And nobody will do a damn thing. Of course, it is the country where fully armed police can shoot - unpunished - a naked man dead by just saying, they felt threatened. This country was built on guns and has never grown up. And on the pretense of defending the country with 1791 mentality everybody needs guns because we can never trust our armed forces to defend us ...in reallity we have just enabled more killers. There is no country in the world that can do it better but the US with the 2nd amendment.
Did you listen to the comments the other day when the media was interviewing the residents of Sandy Hook ?This town was notable for supposedly being known as the SAFEST town in America. So here she is in the SAFEST TOWN IN AMERICA yet she felt so threatened that she felt she needed an arsenal of guns to stay "safe" ? The woman was obviously suffering from paranoia... most likely a FUX SPEWS and NRA induced paranoia. All "gun nuts" suffer from this same kind of paranoia... it's irrational and it's because of heavy rightwing indoctrination to "fear" everyone and everything. They live in some sort of Orwellian timewarp/alternate universe where they have been conditioned to be SO paranoid they suspect EVERYTHING/EVERYONE and will be the first ones to fall prey to BIG BROTHER and start ratting everyone out to their puppetmasters.
recently in the news they are conflicting arguments on this individual. He was very smart, shy, kept in, honor student. now they are saying he had everything physiological problem known to the homo species. if you got any evidence or info on is real state of mind replay.. if you are going to use other media like cnn, fox or the guardian please don't answer
First of all you cannot lump Fux Spews in with "the media".. It's not MEDIA... it's clearly nothing more than a RIGHTWING PROPAGANDA OUTLET. Secondly... I agree about The Guardian... now that they have been corrupted by the American media. They used to be quite credible and unbiased before that.
This is nobody's fault except the person that did it. He was 20, did he have a job? Did he go to school? My fear is he
sat around playing shooting games, practicing killing people. What games were this losers favorite?
In the old days he would have committed suicide, with all the news coverage this coward can be famous.
I pray for all that died and all survivors, may God bless bless America. I hope we don't over react with all kinds of laws,
that will take our freedoms away from the good people.
I am an engineer by degree and profession, but started sub teaching as a retirement plan, Let me tell you, security in Denver suburbs is not great, yes they have a full time officer at the entrance, but the perimeter security is lax at best, also they should add bullet proof doors and windows in them for security to each class room, lock them from the inside, and have escape robe ladders whatever out the windows for added security, too many times I have had strangers, kids, unknown personnel walk in to a class unannounced. There should be perimeter security on the building and on the classrooms.
Airline hijackings started innocently enough back in the 70's and look where it is today! the same progression is happening on schools and any venue, movie, sports, whatever, as we speak, the other big target is cruse ships, and that will happen one day and sooner than later I am afraid with terrorists and drug cartels using submarines! missiles are in the pipeline along with chemicals, and nuclear. We should all fear for our safety, and the government's reaction is to disarm the population, we should be arming up!
The guns are not the problem people with issues are. Someone with a death wish cannot be stopped. A man in China cut the throats of many school children before being stopped. The US killed many Pakistani and Afgan children with their missiles. Mass murderers have been around and will continue to be around. Richard Speck, John Gacy the Hill side strangler and Charles Manson just to name a few. Whats the answer? I dont know. I blame the evil in man himself and only God can prevent this evil form manifesting itself on unsuspecting men.
"Responsible gun owner" -- that's what you all call yourselves. That's what WE call ourselves.
But....shouldn't we be responsible when our guns are accessed, and used in a crime?
Lost, stolen, lent, used by a child or mentally-ill person, whatever.
YOU and WE should be responsible.
Pass THAT as a law, require all weapons to be secured when not in use, and you'll see fewer of these shootings.
There are some that have proposed 'smart guns' which would incorporate RFID, fingerprint recognition, or magnetic ring technology. The gun would only function for the registered owner or owners.
Something like this would prevent someone from stealing other people's guns & using them. Or a bad guy getting the upper hand during a struggle & taking the good guy's gun away & then using it on the good guy.
But the technology would need to be 100% reliable. It wouldn't be any good if you needed to use your gun in a self defense situation & the damn thing didn't fire because it didn't recognize you as the owner.
This technology would have kept this killer from using his mom's guns.
I agree parallelcooler
The part that I really hate now is that the politicians just have to interject themselves into the situation. The governor would do very well and serve his state better if he left all briefings to the State Police.
