A man attending an illegal cockfight in central California died after being stabbed in the leg by a bird that had a knife attached to its own limb.
Jose Luis Ochoa (35) was declared dead at a hospital about two hours after he was injured on January 30, the Kern County coroner said.
An autopsy concluded that Mr Ochoa died of an accidental “sharp force injury” to his right calf.
“I have never seen this type of incident,” Sergeant Martin King, a 24-year veteran of the sheriff's department, told The Bakersfield Californian newspaper.
Mr Ochoa and the other spectators fled when authorities arrived at the scene of the fight. Deputies found five dead roosters and other evidence of cockfighting. No arrests were made.
It was unclear if a delay in seeking medical attention contributed to Mr Ochoa's death.
