On the evening of April 8, 2019, gunfire in Pittsburgh’s Larimer neighborhood left 39-year-old Mark Anthony Jackson dead. Police found Jackson inside a home on the 600 block of Winfield Street; he had been fatally shot and was pronounced dead at the scene. Witnesses reported that 45-year-old Robert E. Harper arrived at the residence demanding to see Jackson, went to the third floor where Jackson was located, and fired a fatal shot through a door after Jackson tried to shut it.

Surveillance footage allegedly shows Harper and an unidentified accomplice fleeing the area, and investigators say Harper had paid a driver to bring him and the other person to Larimer that evening. Pittsburgh police announced Harper’s arrest on April 17, 2019; he was charged with homicide, burglary, conspiracy, and weapons violations while already in the Allegheny County Jail on unrelated charges. Authorities continued to seek information about the second person seen fleeing the scene.

Did anyone in Larimer that night see the vehicle that brought the two men or recognize the unidentified accomplice?
