Nathaniel Walker was 48 and described as a self-taught barber, a devoted father of six, and the foundation of a blended family. He was engaged to be married and had been texting with his fiancée, Nikia Pitts, on the afternoon of his death. A neighbor called him a really nice gentleman who was always smiling.

On the afternoon of April 19, 2024, Walker was inside a home on the 500 block of Lowell Street in the Larimer neighborhood when two masked men entered. A witness told police the men tried to rob him, and one of the intruders shot Walker multiple times as they fled. Emergency responders arrived around 2 p.m. and found Walker deceased; the shooting occurred near a local school as students were returning from a field trip.

Pittsburgh police identified a vehicle seen leaving the area and arrested its driver, 25-year-old Heirkiess Moore-Smith of West Mifflin. Investigators say Moore-Smith drove the two gunmen to and from the Lowell Street home and circled the block while they were inside; he reportedly had his 5-month-old baby in the car. Moore-Smith was charged with criminal homicide, robbery, criminal conspiracy, and endangering the welfare of a child. The two men who entered the home and shot Walker have not been publicly identified or charged.
