Marcello Robertson, 27, was one of three men killed in a mass shooting on April 3, 2017, on the 1100 block of Stiles Street in Philadelphia. According to accounts of the incident, a group of males was approached by unknown individuals who opened fire; Tyair Jabbar and Ronald Fenwick also died and a fourth, 26-year-old man survived. No arrests have been announced and the case remains unsolved.

Family members remembered Marcello as a sensitive person and a father to four children; his grandmother, Sandra Robertson, said she had seen him about 20 minutes before the shooting. Detectives are asking anyone with information to come forward.

If anyone knew Marcello or was in the area that day, can you share what you remember?
