A man dressed in a Santa Claus suit is believed to have murdered six relatives before killing himself in the Fort Worth, Texas suburb of Grapevine on Christmas Day. At the time, police still have no motive, but plan to release the names of the victims today.

This senseless act of violence is the single largest mass-shooting death in the city's history, and among the worst in Texas recently. And it was on Christmas. What's wrong with people?
