Verified Mountain Lion-Human Attacks (1986-2014)

The CDFW defines a mountain lion attack as an incident resulting in direct physical contact between a human and a mountain lion resulting in physical injury or death to the person. The CDFW considers an attack to be verified only when a physician, law enforcement officer or CDFW personnel determine the injuries were caused by a mountain lion.

Note: According to historical reports, four additional fatal incidents involving six victims occurred around the turn of the previous century. Furthermore, two additional incidents have been reported by the media as attacks. However, they do not fit the criteria of verifiable attacks on humans and were not confirmed. One incident involved a turkey hunter who was camouflaged and calling for turkeys when a mountain lion approached from behind. Immediately after the mountain lion confronted the hunter and realized that the hunter was not a turkey, the lion ran away. This is not judged to be an attack on a human. Every indication suggests that if the hunter had not been camouflaged and calling like a turkey, the mountain lion would have avoided him. The other incident on the Los Padres National Forest was described as a mountain lion attack on a boy near a stream. However, the alleged injuries were not verified by a physician, law enforcement officer or CDFW personnel.
