NEWTOWN, Conn., March 14 (UPI) -- Adam Lanza researched mass murders before carrying out the Newtown, Conn., school shootings, sources told the Hartford (Conn.) Courant.
It was previously reported that news articles about Norwegian mass murderer Anders Behring Breivik were found in the apartment Lanza shared with his mother, but Thursday the Hartford, Conn., Courant reported sources close to the investigation now say documents related to other massacres were also found in the residence.
