A Michigan psychiatrist, who was reported missing in December, accidentally drowned in a pond on his property while taking ketamine.

Bolek Payan was seen leaving Henry Ford Allegiance Health in Jackson on December 22, as CrimeOnline previously reported. Investigators saw him leaving his home on foot later that day on security video, and on December 27, they found his body under the ice in the pond.

WILX filed a Freedom of Information Act request for Payan’s autopsy report, which said the cause of death was drowning, with contributing causes of hypothermia and ketamine intoxication. The manner of death was accidental.

According to the Drug Enforcement Agency, ketamine is used to treat resistant depression and is “a dissociative anesthetic that has some hallucinogenic effects.”

The American Addiction Centers says that the drug is rarely overdosed, but it can be associated with accidental injury and death from “falling, drowning, vehicular accidents, and hypothermia.”
