A report released Monday on the Sandy Hook Elementary School shooting reveals chilling details about the day Adam Lanza killed his mother and slaughtered 26 children and educators before taking his own life. The report also details Adam’s obsessions, strained relationships and odd behavior leading up to the shootings.
Nearly a year after the December massacre, this is what investigators say happened:
Acted alone: Adam Lanza acted alone and didn’t conspire with anyone when he killed his mother and 26 children and educators at Sandy Hook Elementary School.
No motive: Investigators conducted many interviews with people who knew Adam and his family. No evidence, the report says, suggests that Adam had a reason to target Sandy Hook Elementary School, which he had attended as a boy.
Obsession with mass shootings: A review of electronic evidence and digital media that “appeared to belong to the shooter” showed he had a preoccupation with mass shootings, particularly the Columbine High School shootings in Littleton, Colo., in 1999.
The weapons: Lanza, 20, was armed with the Bushmaster XM 15-E2S rifle, a Glock 10 mm handgun, a Sig Sauer 9 mm pistol and a large supply of ammunition. He used a Bushmaster XM15-E2S rifle to kill the victims at Sandy Hook before killing himself there with a Glock 10mm handgun. He killed his mother in her bed with a .22-caliber rifle.
10 minutes of terror: Lanza parked his 2010 Honda Civic next to a No Parking zone outside the school and approached the front entrance just after 9:30 a.m. on Dec. 14. The school’s main office staff reported glass breaking at about 9:35 a.m. and saw the shooter. At 9:40:03, the last gunshot was heard. The shot is believed to be the one used by Lanza to commit suicide. At 9:44:47, Newtown police officers entered the school.
Violent video games: Police found numerous violent video games in the basement of the Lanza home. Adam played video games often, both solo and online. He played violent and non-violent games and his favorite at one point was Super Mario Brothers.
Drugs: An autopsy report found no drugs in Adam Lanza’s system.
E-mail only: Nancy Lanza said Adam would communicate with her only by e-mail, although they lived in the same house. She never expressed fear of Adam or concern about her safety, the report said.
Adam Lanza did a drive-by of Sandy Hook: While Nancy Lanza was away, a GPS device in the Lanza home showed that a trip was made between 2:09 p.m. and 2:32 p.m. on Dec. 13, the day before the shootings. The trip was made to and from the “Sandy Hook area” from the Lanza house and was presumable made by the shooter in his black Honda Civic, the report says.
Profile of contradictions: The report says that, “in some contexts,” Adam was viewed as having “above-average intelligence,” and, in other contexts, below-average intelligence. Some people said he had been bullied, but others, including many teachers, said he wasn’t bullied.
Adam Lanza’s father: Adam’s father, Peter, saw him regularly until he was 18. They went hiking and played video games, and went shooting twice. Adam’s relationship with Peter deteriorated in 2010, the last time the two saw one another. Prior to December 2012, Adam stopped responding to his father’s mail and e-mails about getting together.
Emotional problems: Adam disliked birthdays, Christmas and holidays. He didn’t allow his mother to put up a Christmas tree. Nancy Lanza explained this by saying Adam had no emotions or feelings, the report says.
Shooting was a pastime: Shooting was a family pastime, and Adam enjoyed shooting and going to a target range with his mother and brother. Adam and his mother took a National Rifle Association safety course. In November 2012, Nancy Lanza wanted to buy her son a CZ 83 pistol for Christmas and prepared a check for that purpose.
What’s next: With the release of the summary report, “the investigation is closed, and no additional release of information or documents by this office is anticipated,” State’s Attorney Stephen Sedensky III said in a written statement Monday. However, he didn’t release recordings of 911 emergency calls made on Dec. 14., and the Connecticut State Police’s full evidence file about the shootings, which may total thousands of pages, was not released.
