Authorities shot and killed a 2-year-old male cat hours later near where the man's body was found, and were "pretty confident" it was the animal that attacked, said Steve Martarano, a spokesman for the California Fish and Game Department.
Following Thursday's attack, the 13th such incident in California since 1890, the 110-pound mountain lion was to be taken to a laboratory where a necropsy will be performed.
Shortly after 4:30 p.m. Thursday in Whiting Ranch Wilderness Park, a mountain lion pounced on a woman who was riding a bicycle with her friend, said Capt. Stephen Miller of the Orange County Fire Authority.
The lion grabbed Ann Hjelle, 30, by her head and began dragging her. Her friend, Debi Nichols, began screaming for help and grabbed the victim's legs in a struggle to free her.
