Adam Lanza may have hinted at his deadly plans online in the days before last year's Sandy Hook Elementary School massacre.
In documents that were part of a report released Monday, authorities say a Texas woman contacted Hartford police the day of the December 14 attack to say her son had interacted with someone while playing a videogame 20 hours earlier who said there would be a school shooting.
It isn't clear whether she contacted authorities before or after the massacre.
Two days before the shooting, an anonymous user posted comments online saying that they planned to commit suicide Dec. 14 and that it would make the news. The poster said they lived in Connecticut.
The information came from an application for a search warrant for Lanza's computer. Authorities say that the computer's hard drive had been smashed and that nothing usable was obtained.
