Adam Lanza Frequented Gun Message Boards, Obsessively Edited Wikipedia Posts About Mass Shootings

Sandy Hook gunman Adam Lanza, who shot and killed twenty elementary-school children, six adult staffers, his mother, and himself in December, spent his teenage years online talking about guns. A report by the Hartford Courant reveals for the first time the details of Lanza’s Internet life, including postings from 2009 and 2010, when Lanza was 17, on firearm message boards and Wikipedia entries about mass shootings. They are haunting.

On the listing for Kip Kinkel, who killed his parents and shot 27 people at a high school in 1998, Lanza, as Kaynbred, again specified the weapons used:

Oddly enough, Anders Breivik, the man who killed 77 people in Norway’s 2011 massacre and was himself an object of fascination for Lanza, also had a thing for editing Wikipedia articles.
