City police today were seeking a motive and a suspect in the shooting death last night of a 23-year-old man whose body was found in the hallway of a rowhouse in the 1600 block of Harlem Ave.
Police said that when Officer John Tiel of the Western District arrived at the front of the house at 11 p.m. in response to a shooting report, he was unable to gain entry through the front door and went to the rear alley.
There, Tiel met a woman who told him a man had been shot and was lying inside the house.
Police said Tiel entered the house, and, in a hallway lying a few inches from the front door, he found the body of Gary Tyrone Mayo of the 1600 block of W. Mulberry St.
Tiel said Mayo was lying face down bleeding from a gunshot wound to the base of the skull.
Mayo was pronounced dead at the scene by the crew of a city fire department ambulance several minutes later.
A paring knife and a flashlight were under the body, Tiel said.
Outside the house in the alley, Tiel later found a 10-inch knife, which was seized as possible evidence.
Police said it was unclear why Mayo was in the house and why he was shot.
