A Bentonville man who committed suicide this week died from ingesting cyanide, officials said Thursday (March 21).

Police have identified the man as Timothy Mooney, 31, of 11 Ivy Circle. Property records show the home belongs to Timothy and Amelia Mooney. Amelia filed for divorce from Timothy on March 5, according to Benton County Circuit Clerk records.

In a news release,¬†Bentonville Police Chief Jon Simpson said parts of the investigation are still ongoing, but “we have determined the manner of death was suicide by cyanide poisoning.”

The Arkansas Department of Health determined substances found near the body were cyanide, the release states.

Investigators are attempting to learn where the man obtained cyanide, said Bentonville Police Capt. Justin Thompson.

Cyanide attacks respiratory cells, shutting down the body’s ability to absorb oxygen, said Daniel Oxford, Benton County coroner.

He said the scene where the incident occurred and surrounding area are safe and pose no public threat. Only people in an enclosed area at the time of the incident would have been exposed to a possible hazard, Oxford said.

“There is absolutely no threat,” he said. “The scene has been deemed safe.”

The man’s remains have been cremated, Oxford said. The cremated remains pose no cyanide threat to anyone who handles them, he said.

Bentonville police conducted a welfare check of the home Tuesday and noticed a note on the front door indicating a suicide had taken place inside the house, according to Bentonville police.

Police said the man claimed in the suicide note that he was going to kill himself using cyanide.
