Police are still trying to determine the man's identity.
The death of a man who was found with a fatal gunshot wound to the head Thursday morning behind the Walmart store along Foxcroft Avenue in Martinsburg was ruled a suicide by the state medical examiner's office in Charleston, W.Va., police said Friday.
The suicide happened about 12:45 a.m. on Tuesday, police said.
Martinsburg police are still trying to determine the identity of a man, Martinsburg Police Cpl. Scott Doyle said in a news release Friday.
Officers who responded to the rear of the store at 8:59 a.m. found the body lying between stacks of recycled debris next to a Ruger .38-caliber revolver, according to a police department news release.
An investigation determined that the man, who had been lying there for several hours, had suffered a single gunshot wound to the side of the head, police said. One round had been fired from the gun.
Doyle said police do not believe anyone else was in danger at the time of the shooting.
At 10:30 a.m. Thursday, the parking lot of the Walmart at 800 Foxcroft Ave. was full of vehicles. Customers entered and exited the store as usual.
Walmart spokeswoman Kayla Whaling had said in a voicemail message that the company was referring questions to Martinsburg police.
The body was described as a white male in his 50s with balding white hair, police said. He was wearing a red polo shirt, black jeans, a gray zipped hooded sweatshirt, a fanny pack and black shoes. Officers said they believed the man was physically impaired in his left hand.
Anyone with information may call the Martinsburg Police Department at 304-264-2100.
