Which Video Game Was This Kid Playing

A seven year old Australian kid broke into a zoo and then decided to kill a couple lizards and then feed animals to the crocodile. Because of the laws within the region, the seven year old can not be charged however, the zoo owner is planning on suing the parents.

How long will it take mainstream media to tell us that prior to the incident, the kid was found to be playing some sort of violent video game and therefor, the video game is to blame, not the kid?
