A woman who befriended Adam Lanza online prior to the 2012 shooting said he was "focused and obsessed with mass murders and killing sprees". "The shooter was fascinated with past shootings and researched them thoroughly".
The documents said Lanza found food unappealing and complained about being unable to find clothing that fit him comfortably.
The behavioral analysis unit document did not say what evidence there was that Lanza had a pedophilic interest in children.
In a separate interview, another unidentified person told investigators Nancy Lanza turned down a marriage proposal from a man she was dating "because she would have had to move [redacted] and she would not leave Adam", according to the documents. Many people are unaware of that there are specific signs that people give off that can indicate a violent act is imminent'. He killed his mother in her bed at home, where he also lived, before making his way to the school where he murdered 20 children and six teacher. They also reportedly found a screenplay about a relationship between an adult male and a young boy. Lanza told her that adult-child sexual relationships might be "possibly beneficial to both parties".
Numerous documents had large sections redacted and included reports by agents who interviewed people about shooter Adam Lanza, who killed himself as police arrived at the school. There are also investigations into potential copycat killers, people who had made threatening calls to Sandy Hook Elementary or wrote inflammatory things online, and odd, vaguely threatening emails sent to a CT newspaper.
The woman told investigators that Lanza was "extremely intelligent" but depressed and cynical, with a negative view of the world.
At the point when experts with the Central Intelligence Agency and Federal Bureau of Investigation appeared at their home, Nancy Lanza persuaded the officers that "her child was quite recently exceptionally keen and was testing himself to check whether he could hack into an administration framework", as indicated by one of the records. The writings offer insight into what motivated Lanza to murder 26 people on December 14, 2012.
Another source said that Lanza rejected the medication he was provided for his Asperger's syndrome condition, a diagnosis he also rejected.
Another family friend told agents that while in school, Adam Lanza was "bullied, but not excessively, for his social awkwardness and his physical gait". The person said Lanza had no friends, was computer savvy and became very interested in firearms.
The rifle and two handguns - found next to his body - as well as an Izhmash Saiga-12 12-gauge semi-automatic shotgun recovered in his vehicle were legally purchased by his mother, whom the documents described as a "gun nut".
The man says he went to the Newtown Police to report the threats, but they told them there was nothing they could do since Lanza's mother was the official owner of his weapons cache.
"The authorities told Nancy that if her son was that smart he could have a job with them one day". She said Lanza wrote about mass killers with respect and understanding, saying such attacks were merely the symptoms of a broken society. To read them, click the links below.
