PORTLAND, Ore. (AP) — Sheriffs officials say the animal that killed an employee this weekend at an Oregon animal sanctuary was a cougar, and an autopsy shows the woman died of multiple bite wounds.

Dr. Christopher Young of the Oregon State Medical Examiner's Office said Monday that 36-year-old Renee Radziwon of Portland had "devastating injuries in the critical areas of head and neck."

Radziwon died Saturday night inside an enclosure at WildCat Haven in Sherwood, where she was the head keeper.

The sanctuary said in a statement Sunday that while protocol calls for more than one worker inside an enclosure containing an animal, Radziwon was apparently alone.

Radziwon's mother told The Associated Press her daughter had expressed concerns about safety measures at the sanctuary before the attack.
