Students outside Sandy Hook Elementary School in Newtown, Connecticut, where a school shooting was reported
HARTFORD, Conn. (AP) The prosecutor who led the investigation into the Newtown school shooting says it did not determine a motive for the attack.
State's Attorney Stephen Sedensky III says there is also no clear indication why he chose Sandy Hook Elementary School as the target for his rampage other than the fact that it was close to his home.
He said the gunman, Adam Lanza, had significant mental health issues that affected his ability to live a normal life and interact with others but did not affect his mental state for the crimes.
He said police went into the school within minutes of the first shots being fired and that along with the actions of teachers inside saved many children's lives.
Lanza also may have hinted at his deadly plans online in the days before the massacre.
In documents that were part of the report, authorities say a Texas woman contacted Hartford police the day of the Dec. 14 attack to say her son had interacted with someone while playing a video-game 20 hours earlier who said there would be a school shooting.
It isn't clear whether she contacted authorities before or after the massacre.
Two days before the shooting, an anonymous user posted comments online saying that they planned to commit suicide Dec. 14 and that it would make national news. The poster said they lived in Connecticut.
The information came from an application for a search warrant for Lanza's computer. Authorities say that the computer's hard drive had been smashed and that nothing usable was obtained.
The report also shows that Lanza had an obsession with mass murders, in particular with the April 1999 shootings at Columbine High School in Colorado.
Lanza killed his mother inside their Newtown home before driving to Sandy Hook Elementary School and carrying out his rampage. He committed suicide as police arrived.
