The court papers were made public Monday. The divorce between Nancy and Peter Lanza 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. According to the Stamford Advocate, Peter Lanza is an executive at General Electric who re-married and lives in Stamford, Conn.

The agreement makes no mention of any mental health issues regarding Adam Lanza.

On Saturday, Peter Lanza issued the following statement:  "Our hearts go out to the families and friends who lost loved ones and to all those who were injured. Our family is grieving along with all those who have been affected by this enormous tragedy. No words can truly express how heartbroken we are. We are in a state of disbelief and trying to find whatever answers we can. We too are asking why. We have cooperated fully with law enforcement and will continue to do so. Like so many of you, we are saddened, but struggling to make sense of what has transpired."
