A preliminary investigation into the death of a University of Georgia international student revealed he may have committed suicide, according to notes in an university incident report.

Lei Wang, 35, was found dead about 4 p.m. Tuesday, a day after his wife told police Wang was missing. Police said there was no indication of foul play.

Wang’s wife, Huiling Wei, told police her husband had earlier threatened to commit suicide, according to the incident report university police spokesman Bob Taylor forwarded The Atlanta Journal-Constitution on Wednesday.

Wei said her husband, who worked in a veterinary lab in Athens, had been depressed for years and often said he would kill himself, according to the report.

She became worried when her husband seemed to switch his normal routine. The couple normally met up about 5 p.m. to pick up their 5-year-old daughter, Wei said. Wang did not have a car, so he almost always told his wife when he wouldn’t be able to meet her.

Hours after their scheduled 5 p.m. meeting time on Monday, Wei hadn’t heard from her husband.

He had reported to work at the Veterinary Medicine Hospital, a woman who sat next to him at the lab told authorities.

She said she asked Wang about work she needed. He opened his computer, pulled up the work, told her to email it to herself, then left a short time later. She did not see him again.

Wang was later found dead in a wooded area near College Station Road.
