In March 2008, thirty-nine-year-old Robert Lyons savagely attacked and killed his mother in their condominium, by bludgeoning her with a cognac bottle and stabbing her. At his trial, prosecutors said that he snapped; the two were prone to profane arguments on a fairly regular basis, and Robert had a lot of anger against his mother. But what had finally pushed him past his limit?It turns out that it was his mother’s failure to call a friend who had Skybox-seating tickets to an upcoming concert Robert wanted to see.We’ve all been disappointed when we couldn’t see a much-anticipated show, but we can’t imagine a more severe overreaction than this. What dark forces swirled inside this man? Who did he want to see so badly that his mother’s failure to procure tickets could have driven him to a murderous, bloody rage? Slayer, perhaps? Cannibal Corpse? Napalm Death?Nope. He had wanted to see Avril Lavigne. And although it would be more plausible that a middle-aged man would kill his own mother to avoid an Avril Lavigne concert, we stand by our sources.
