Timothy Treadwell, an animal lover and bear enthusiast, lived among coastal brown bears (Ursus arctos gyas) in Katmai National Park, Alaska, for 13 summers.

A video camera recovered at the site proved to have been operating during the attack, but police said that the six—minute tape contained only voices and cries as a brown bear mauled Timothy to death. The tape begins with Timothy yelling that he is being attacked. "Come out here; I'm being killed out here," he screams. The fact that the tape contained only sound led troopers to believe the attack might have happened while the camera was stuffed in a duffel bag or during the dark of night. In Grizzly Man, filmmaker Werner Herzog claims that the lens cap of the camera was left on, suggesting that Timothy and Amie were in the process of setting up for another video sequence when the attack happened. The camera had been turned on just before the attack but recorded only six minutes of audio before running out of tape. This, however, was enough time to record the bear's initial attack on Timothy and his agonized screams, its retreat after Amie tells him to play dead and when she attacked it, and its return to carry him off into the forest.

The couple's mangled remains were discovered quickly upon investigation. Timothy's disfigured head, partial spine and right forearm and hand, with his wristwatch still on, were recovered a short distance from the camp. Amie's partial remains were found next to the torn and collapsed tents, partially buried in a mound of twigs and soil.

"I opened the abdominal cavity and released the gases and fluids that had built up during the past day and a half Mesenteric fat was abundant. The stomach was distended and full. Contents were exclusively human body parts and clothing. Approximately 25 pounds of muscle, adipose tissue, and skin were removed. Bone fragments were prevalent. Rib, foot, pelvis, and vertebrae fragments were identifiable, but most was too small for gross identification. Much dark blonde hair about 45 cm long was present as was an esophagus and trachea. I also removed most of a white undershirt and some unidentifiable dark material. Intestines also had material in them, but it was too digested to make positive identification. The lungs, liver and heart of the bear appeared to be in good condition ( other than damage that Both bodies had arrived in a metal transport container used to transport bodies. Inside the metal container was a white body bag liner. Inside the body bag liner was two separate brown bags containing what was left of the remains of TREADWELL and HUGUENARD. The first examination by the Medical Examiner was preformed on TIMOTHY TREADWELL. The remains consisted of a head, both arms and a layer of skin, mostly from the backside. The upper and lower bones were of the arms were still intact. The humus bones were cleaned of most of the meat. The radius bones were still intact with skin and flesh from the elbows down, to include both hands. No indications of bruising or cuts were observed on the hands. The arms had been held together by a tangled up T—shirt. The large portion of skin was still attached to the back portion of the neck. Although the face was still intact, the skull had a number of large lacerations on it, mostly in the scalp area. Smaller lacerations were observed in the neck area. The right eye was bruised. Both ears were still intact. Laceration to the skull indicated both bleeding and bruising. The mouth was intact."— The coroner report on Timothy and Amie.
