Around 4:13 p.m. Friday, Huber Heights police officers responded to reports of a possible arson in the 6400 block of Chambersburg Road.
A 911 caller said that there had been gasoline spread inside a tattoo business and set on fire, but that their boyfriend had put out the flames.
During the investigation, a separate call was received for a male with a gunshot wound to the head, police said.
A different 911 caller told dispatchers that they had seen a man with a gun lying in a playground who didn’t respond when they called out to him.
The man was later identified as Barker. He was found in the 6100 block of Chambersburg Road, according to the coroner’s office.
“At this time, it is believed the two calls are connected, and Huber Heights detectives are working both scenes,” police said.
No other details were immediately available.
