Although Lanza did not use his name, investigators linked the poster's user name to Lanza, according to sources familiar with the probe of the Dec. 14 shooting at Sandy Hook Elementary School. The same user name appears in the Wikipedia edits, discovered by The Courant. A Wikipedia spokesman said the website could not identify the poster, citing privacy policies.

The poster appears to be part of a video gaming "clan," communicating with the others through myshoutbox.com in February 2010. At one point, some fellow gamers appear to be lamenting the departure of the poster, and of others, from the clan.
