Following an 11-month investigation, the motive of the shooter who killed 20 children and six adults at a Connecticut elementary school last December before killing himself is not known, says a heavily redacted report (PDF) released Monday by the state’s attorney in Danbury.
However, it says 20-year-old Adam Lanza had “significant mental health issues” and was obsessed with mass murders when he shot his mother to death in the home they shared and then proceeded to Sandy Hook Elementary School, where he fired 154 rounds from a Bushmaster .223-caliber rifle in five minutes before committing suicide, according to the Nation Now page of the Los Angeles Times (sub. req.) and the New York Times (reg. req.). Weapons he used were legally purchased by his mother.
Because Lanza acted alone, there will be no criminal prosecution, the report says.
Meanwhile, New Britain Superior Court Judge Eliot Prescott said at a Monday hearing that he is going to listen to recordings of 911 calls before deciding whether to make them public. The Associated Press has sought the recordings, saying that they are ordinarily made public and would shed light on police response to the shootings. State officials have resisted doing so, arguing that the recordings will reopen wounds among those who suffered from the tragedy.
