Internet fraudsters are faking messages by Sandy Hook killer Adam Lanza. What lies behind this sick fetish?

Several newspapers have speculated that Sandy Hook Elementary School shooter Adam Lanza may have anonymously revealed to the internet what he planned to do. Screenshots purportedly of posts on a 4chan message board show a user intending to kill himself in a way that will make the news on Friday morning, saying only that he lives in Conneticut (sic). The post is accompanied with an uncensored photo of Eric Harris and Dylan Klebold, the Columbine school killers, after they had committed suicide.

However, the screenshots are unquestionably fakes.
