A small town north of San Antonio is mourning its mayor, who was kicked and trampled to death by a 500-pound donkey. Police say Hollywood Park Mayor Bill Bohlke, 65, was attacked by a stud donkey he kept on his cattle ranch. He was found dead about 50 yards from his truck, which was still running. Male donkeys "can become very aggressive, very mean, sometimes triggered by a female in heat," a police spokesman tells the San Antonio Express-News. “We'll probably never know what triggered it, but it was evident that this particular donkey was involved, based on the evidence at the scene and what we saw on this donkey." Bohlke, who was retired from the Air Force, was elected in May in his first run for public office.
