Before Adam Lanza killed 20 children and six adult staffers at Sandy Hook Elementary School in Newtown, Conn. (and his own mother), he was a prolific contributor to gun message boards and was obsessed with editing Wikipedia articles about illustrious mass murderers.
Investigators have linked Lanza to multiple postings across several websites written from April 2009 to February 2010, reports the Hartford Courant. In the posts, the author demonstrated a technical mastery of high-capacity guns and a fixation for his favorite kind of bullet.
The posts also show a nearly chatty personality that differs markedly from the creepy, shunned loner typically portrayed since the horrific shooting.
The cold-blooded killer, who would have been 17 years old at the time of the posts, didn’t use his real name. The Courant says it won’t release any usernames Lanza used.
The user believed to be Lanza painstakingly revised 12 Wikipedia articles about gun massacres that had recently occurred around the world.
One entry details the weapons 15-year-old Kip Kinkel used to murder his parents and then kill two students and wound a couple dozen more at his high school near Eugene, Oregon.
Lanza appears to have edited information in another Wikipedia article about the gun Kimveer Gill used in a 2006 shooting at Dawson College in Montreal. According to the Courant, the poster investigators say is Lanza explained his revision by noting: “‘9mm’ was listed as ‘.9mm.’ People say that 9mm is anemic, but this is ridiculous.”
The same poster modified entries on a 1991 mass murder at Luby’s cafeteria in Killeen, Texas,, when George “Jo Jo” Pierre Hennard shot 50 people as well as the 1988 shooting at ESL Incorporated in Sunnyvale, Calif.
The Courant notes a number of conspicuous similarities between the ESL Incorporated rampage and Lanza’s mass killing.
Lanza also amended the Wikimedia pages on two mass shootings that occurred at shopping centers—one in Omaha, Neb. and the other in Helsinki, Finland.
Lanza also liked to post in gaming chat rooms and on various gun message forums including glocktalk.com and thehighroad.org.
The poster investigators say is Lanza discussed Connecticut’s various gun laws, for example, and suggests appropriate gifts for gun enthusiasts.
In a thread a late-night thread at thehighroad.org in 2009, the poster suspected to be Lanza admitted “a fetish for .32 ACP.”
At glocktalk.com in April 2009, he apparently once had a computer-related question.
“Am I just an inattentive philistine or has additional RAM in a computer which was not already deprived of it never helped any of you?” the poster queried.
In other posts, the poster who may have been Lanza offers YouTube links to a commercial from the 1970s laughing doll and to The Rock-afire Explosion, the Showbiz Pizza Place animatronic robot house band from the 1980s featuring at least two bears and a silverback gorilla.
