Newtown gunman Adam Lanza may have corrected several Wikipedia articles about mass murderers and alluded to a bullet "fetish."
After the Dec. 14 shooting at Sandy Hook elementary school in Newtown, Conn., investigators uncovered past posts on numerous websites by a user believed to be Lanza, The Hartford Courant reports.
The Courant didn't release the username, but the newspaper reviewed several dozen posts from April 2009 to February 2010. Lanza would have been 17 years old at the time of the posts.
If the posts were indeed made by Lanza, they're some of the first of his writings to be publicly available.
On thehighroad.org in 2009, a poster believed to be Lanza asked whether a ban on a semiautomatic pistol would apply to other weapons. Someone responded suggesting that he ask Connecticut police.
"I always prefer asking through proxy when I can avoid speaking to someone directly. I was just wondering if anyone knew because I have a fetish for .32 ACP," he reportedly said, referring to a type of ammunition.
During the same yearlong span, the same user corrected details on 12 Wikipedia entries about mass shootings around the world. They included changing the weapon used in the Dawson College shooting in Montreal in 2006, the Daily Mail reports.
The user's interest in mass shootings falls in line with revelations that Lanza was studying other crimes. Shortly after the Sandy Hook shooting, investigators found literature in his home about other mass shootings.
Lanza killed his mother at their home on Dec. 14 before killing 20 first-graders and six staff members at Sandy Hook Elementary School in Newtown. He then turned the gun on himself.
