A final report released by the state's attorney for the Judicial District of Danbury on Monday found that Sandy Hook Elementary School shooter Adam Lanza had no apparent motive for gunning down 27 people on Dec. 14, 2012, in Newtown, Conn., including 20 children, six school officials, and Lanza's mother.

Lanza's struggle with mental illness — documented at length in the final pages of the report — was "no defense to his conduct," according to investigators. Beyond proximity, there was no clear reason why Lanza chose Sandy Hook Elementary School as his target.

"What we do know is that the shooter had significant mental health issues that, while not affecting the criminality of the shooter's mental state for the crimes or his criminal responsibility for them, did affect his ability to live a normal life and to interact with others, even those to whom he should have been close," wrote Danbury State's Attorney Stephen J. Sedensky III.

6. There were disturbing items found in the shooter’s room, including three photographs of a dead human covered in blood, and photocopied newspaper articles from 1891 about a school shooting involving children.

7. Lanza had a preoccupation with mass shootings, in particular the Columbine shootings. He kept a spreadsheet with information about mass murders, listing information about each shooting.

9. On Dec. 13, 2012, the day before the shooting, Lanza visited Sandy Hook from 2:09–2:32 p.m.

10. Before the shooter left for Sandy Hook, he significantly damaged his hard drive. Forensic experts still cannot recover any information from it. Should information be obtained from the hard drive, the case will be reopened.

12. Lanza shot his mother before 9:30 a.m. on Dec. 14. Neighbors assumed the shots were from hunters and didn’t report them. Between 9:30 a.m. and 10 a.m., a delivery was made to the house; the driver left a slip and continued on.

14. All victims were given autopsies on Dec. 15, 2012. The cause of death for every victim was determined to have been gunshot wounds. All deaths were named homicides.

16. Lanza's likes and dislikes were erratic. He didn't like birthdays, Christmas, holidays, getting his hair cut, and certain types of dishes.

17. He liked building computers, playing video games and the saxophone, writing poetry, and hiking, according to the report. Shooting was considered a family pastime, and Nancy and Adam Lanza both took NRA safety courses.

19. Though Lanza's mother said he "had no emotions or feelings," acquaintances said he was "capable of laughing, smiling and making jokes, though always in a dry fashion." He never talked of being bullied.

20. Lanza was a Sandy Hook student from 1998 to 2003, but he "was never assigned to the classrooms where the shootings occurred."

23. "The total weight of the guns and ammunition from the shooter at [Sandy Hook Elementary School] was 30.47 lbs."

25. On the day of the shooting, several Newtown residents received voice messages — all from out of state — saying, "I am Adam Lanza and I am going to kill you.”

An appendix to the report contains photos from Sandy Hook elementary school and Nancy Lanza's home at 36 Yogananda St. in Sandy Hook.
