(AP photo) -- The state's attorney report on the horrific murders at the Sandy Hook Elementary School by shooter Adam Lanza found no "conclusive motive" for his actions but did document unsettling facts about the 20-year-old killer, including computer files he kept on the rights of pedophiles, a movie about man/boy love, instant messages concerning "homosexual fantasies," numerous mass murder documents, and a computer game entitled "School Shooting." -- The state's attorney report on the horrific murders at the Sandy Hook Elementary School by shooter Adam Lanza found no "conclusive motive" for his actions but did document unsettling facts about the 20-year-old killer, including computer files he kept on the rights of pedophiles, a movie about man/boy love, instant messages concerning "homosexual fantasies," numerous mass murder documents, and a computer game entitled "School Shooting."





In "School Shooting," an amateur computer game, "the player controls a character who enters a school and shoots at students," reads an Investigation Report (DPS-302-E) that is among the 1,000-plus pages comprising the state's attorney report on the shootings.

In his summary report, State's Attorney for the Judicial District of Danbury Stephen Sedensky says the "shooter had significant mental health issues" but "the shooter's mental status is no defense to his conduct as the evidence shows he knew his conduct to be against the law. He had the ability to control his behavior to obtain the results he wanted, including his own death."





The summary report states that in the electronic evidence gathered at Lanza's house from his computer, "investigators found many things that are on a typical hard drive or memory card" but, "That being said, the following selected topics or items were found within the digital evidence seized."





Some of the items listed include:





" Commercial movies depicting mass shootings."

" The computer game titled 'School Shooting' where the player controls a character who enters a school and shoots students."

" Five-second video (dramatization) depicting children being shot."

" Materials regarding the topic of pedophilia and advocating for rights of pedophiles (not child pornography)."

Along with the summary report is a "Review of Electronic Evidence" Investigation Report based upon an analysis of a USB hard drive that belonged to Adam Lanza. Among the numerous folders and sub-folders, investigators found a Text document entitled "pbear," a document "written advocating pedophiles' rights and the liberation of children." (See Investigation Report.pdf





There also was a "writing" document entitled "Lovebound," which is described as a "screenplay or script describing a relationship between a 10-year-old boy and a 30-year-old man." This manuscript was apparently written by Lanza, according to the report.







The review also lists the following:





" 457.full Profile of a pedophile."

" 226972 (AVI) Voor Een Verloren Soldatt -- movie depicting a man/boy relationship."

" colgam01 Spreadsheet ranking mass murders by name, number killed, number injured, types of weapons used, and disposition."

" 'me' 8-page Word document detailing relationships, ideal companion, culture, voting, personal beliefs, describes doctors touching children as rape."

" 'umm' Word document detailing how marriage is abusive and negative to people in a relationship." (See Investigation Report.pdf





The movie Voor Een Veroloren Soldatt (For a Lost Soldier) is a 1993 Dutch film that tells the story of a sexual relationship between a 12-year-old boy and a Canadian soldier in the Netherlands near the end of World War II.

New York Times, is a gay " The movie, as described in 1993 by the, is a gay " coming of age " film without "any implied accusation of child abuse. ... [T]he film assigns no blame and assesses no damages."





In a folder entitled "Smigglesnsuch," there is an "Instant Message history with SixteenBitElder 'The Stranger' and 'Smiggles' (presumably the shooter) from December 2010 - February 2011. Discussion that focuses on gaming, homosexual fantasies, and day to day activities."





There also is a text file called "Selfish," a "Word document explaining why females are selfish."

There also is a video of a dancing "pedobear."





A pedobear is an illustrated teddy bear image that programmers originally designed several years ago to flag child pornography or material deemed sexually inappropriate for children, but which has sometimes been used by child pornographers to draw attention.





The game on Lanza's hard drive, "School Shooting," apparently was not a commercial product; the state's attorney has not provided any further information on the game.

In the report, some witnesses told investigators that Lanza, in ninth and tenth grade, was reclusive, "shutting himself in the bedroom and playing video games all day."





"Reportedly, the shooter did not drink alcohol, take drugs, prescription or otherwise, and hated the thought of doing any of those things," reads the report. In addition, the "shooter disliked birthdays, Christmas and holidays. He would not allow his mother to put up a Christmas tree."





According to the FBI interview reports, one witness "recalled ADAM [Lanza] was very concerned about the environment and ADAM would walk around the island [redacted] picking up trash."





The same witness said Lanza "was very particular about what he would eat. ADAM was initially a vegetarian and then became a vegan."
