David Henry Porter, 42, was fatally shot multiple times in the head and neck inside a northeast Baltimore barbershop on the night of November 9, 2013, at about 10:30 p.m. The shooting occurred in the 4400 block of Frankford Avenue. Police released surveillance video showing a person they identified as the shooter just before the fatal encounter and warned the individual should be considered armed and dangerous and remained at large.

Born July 17, 1971, and raised in Baltimore, Porter was known to family and friends as Muppy. A Frederick Douglas High School graduate, he wrote poetry, had an interest in design, worked at times as a used car salesman, and was remembered as a peacemaker who put others first. He was a devoted father and close to his mother and his only brother, Sean.

Does anyone who was in or near the 4400 block of Frankford Avenue that night have information that could help investigators?
