Man accused of killing mom over Avril Lavigne tickets

A trial is underway for a man who prosecutors say murdered his mother because she wouldn't get him tickets to see Avril Lavigne in concert. Robert Lyons, 39, is accused of hitting his mother in the head with a bottle and stabbing her to death with a knife. There's also claims he poured household cleaners on her body and changed her clothes. Lyons' defense says he suffers from this mental disorder and was "provoked" by his mother after she held a knife to his face.
