Conn. police release final report on Newtown school shooting

NEW YORK (CNN) -- A final report released Friday on the investigation of the mass shooting at Connecticut's Sandy Hook Elementary School offered snippets of information into the life of the reclusive and tormented young man who carried out the second deadliest mass shooting in U.S. history.

More than anything, the voluminous report -- thousands of pages long -- from the Connecticut State Police closes a final chapter on a massacre that triggered a national debate over gun violence, school safety and mental health.

In a heavily redacted page in the report, an unidentified witness told investigators 20-year-old gunman Adam Lanza hated his mother, Nancy, and Sandy Hook Elementary School. She volunteered at the school from 1998 to 2012, including years when he attended it.

"Lanza apparently felt that his mother loved the students more than him," the report said.

However, a prosecutor's report released last month concluded that Lanza acted alone and took the motive for the bloodbath to his grave.

Mostly, Friday's report offers slight glimpses into the Lanza household.

Nancy Lanza discussed her son's "disabilities" with a friend the day before her son shot and killed 20 first-graders and six staff members at the Newtown school.

Lanza, 20, killed the children and staff with a semi-automatic on December 14, 2012. Earlier, he killed his mother inside their home. He committed suicide with a handgun as police arrived at the school.

One of the responding officers at the school found a group of students and a teacher hidden in a small bathroom blocked behind a bookshelf, Friday's report said. The teacher did not initially believe police had arrived. An officer slid his badge under the door.

One of Lanza's former teachers told investigators that during what were supposed to be brief creative-writing assignments, the young man produced long, disturbing passages.

"Adam would write ten pages, obsessing over battles, destruction and war," the teacher said, according to the report. His work was "so graphic that it could not be shared."

After the shooting, the items investigators removed from the Lanza home included a military-style uniform that was found in Adam Lanza's room. There were books with titles such as "Look me in the eye: My life with Aspergers," "Born on a Blue Day: Inside the Mind of an Autistic Savant," and the "NRA Guide to the Basics of Pistol Shooting."

In text messages in Nancy Lanza's phone records, the mother expressed concerned for her son while texting with friends.

"I REALLY wish I could but I have so much to do and want to spend a little extra time with Adam before I go," she wrote in one. "Also, lots of cooking to do because I like to leave him with all his favorites."

In another, she writes, "I was off to a rough start. Poor Adam bumped his head (really badly) and we were dealing with blood at 5:30 in the morning :) He is ok... It looked worse than it actually is."

Earlier this month, a prosecutor's report on the case said Lanza "had significant mental health issues that affected his ability to live a normal life and to interact with others."
