A woman who called 911 said she saw a man lying in a yard while she was driving by and was concerned, according to Montgomery County Regional Dispatch Center records.
Dungey had been the victim of an aggravated robbery at about 11:30 a.m. the same day, when he was robbed at gunpoint, Bauer said.
It is not clear whether the robbery and the man’s death are related.
