In September 2006, Thompson and attorney Steven Sanders filed a suit in Albuquerque, New Mexico, against Sony, Take-Two, Rockstar Games, and teenage killer Cody Posey, for the wrongful death of three members of Posey's family. The suit, on behalf of surviving family members, claimed that "obsessively" playing "Grand Theft Auto: Vice City" made violence "pleasurable and attractive," disconnected violence from consequences, and caused Posey to "act out, copycat, replicate and emulate the violence" when in July 2004 he shot and killed his father, stepmother, and stepsister and then buried them under a manure pile. According to Thompson, "Posey essentially practiced how to kill on this game. If it wasn't for "Grand Theft Auto," three people might not now be dead."
