A grizzly bear featured in the recent Will Ferrell film "Semi-Pro" and touted as one of the "best trained" in show business has killed its handler, but officials said on Wednesday they were puzzled by what provoked the attack. I have a few ideas. You morons.

The 700-pound bear, which stands 7 1/2 feet tall, bit Stephan Miller, 39, in the neck on Tuesday at a facility where wild animals are trained for film and TV productions near the mountain resort of Big Bear Lake, east of Los Angeles.

Two other trainers at the facility, called Randy Miller's Predators in Action, subdued the bruin with pepper spray and were unhurt in the incident, said San Bernardino County Sheriff's Department spokeswoman Arden Wiltshire.

Authorities said that assuming no wrongdoing turns up in the investigation, it would be left up to the owners of the bear to decide whether to destroy it or keep it alive.
