The suspect arrested Tuesday night for the series of dry ice bombs that exploded at Los Angeles International Airport is Dicarlo Bennett, a 28-year-old employee of a ground-handling contractor at the airport. He allegedly took the dry ice off a plane, where it was being used to cool food, and put it in a plastic bottle in an employee bathroom Sunday and another, similar device on the tarmac Monday, a source told the Associated Press. No theories yet as to why.
