NEWTOWN (WKOW) -- New details are emerging about the Sandy Hook Elementary school shooter's mother. The shooter, Adam Lanza's mother Nancy Lanza had authority to make decisions regarding his upbringing, after a divorce from his father.
The newly released paperwork shows that Nancy Lanza's divorce was finalized in September 2009, when Adam Lanza was 17.
Lanza killed his mother before going to Sandy Hook Elementary School in Newtown, Conn., on Friday morning and killing 20 children and six adults before taking his own life.
His parents married in June 1981 in Kingston, N.H. The file says their marriage broke down "irretrievably" and that there was no possibility of getting back together.
The divorce agreement gave Nancy Lanza $265,000 in alimony last year. It makes no mention of any mental health issues regarding Adam Lanza.
