Florida video game gunman's dark obsession with hobby

A 24-year-old gunman who attacked a Florida video game tournament was so obsessed with his pastime he would refuse to bathe or go to school, according to court records. David Katz had a history of mental illness, according to his parents' divorce filing in his home state. His mother once confiscated his console and locked it in her room, and he punched a hole in the door, she said. Katz killed two people on Sunday before fatally shooting himself, police say. According to court papers in Maryland, he had a longstanding feud with his mother, and had twice been hospitalised for mental illness.
