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.
Documents show Lanza wrote a violent book in the fifth grade that included passages in which a character shoots his mother in the head.
The homemade manuscript is titled "The Big Book of Granny" and was among items seized from Adam Lanza's home. Details are in documents that were part of a report released Monday.
Lanza killed 20 first-graders and six educators with a rifle in Sandy Hook Elementary School in December. He fatally shot his mother in the head, then drove to the school, carried out the killings and committed suicide.
The documents say the main character in Lanza's book has a gun in her cane and shoots people. There's nothing to indicate Lanza ever handed the book in at school.
The son character sinks his mother to the bottom of the ocean with a "cement floatation device." Another character likes hurting people, especially children.
