An autopsy revealed that a man found eaten by a bear in the national park, Great Smoky Mountains, died of a methamphetamine overdose before the bear attacked him.

In September, officials discovered the body of William Lee Hill Jr., 30, when a bear was feeding on his body in the national park.

According to park officials, the definitive cause of death was unknown at the time, so it was decided to euthanize the animal for public safety reasons and understanding why the bear was behaving aggressively.

On Monday, the Knox County Regional Forensic Center reported that the cause of Hill’s death was “accidental methamphetamine intoxication”.

Hill, who had a history of drug abuse, went to the park with his best friend,
Joshua David Morgan, to illegally harvest ginseng, but became separated, the newspaper reported.
