Armone Stanley was 34 when he was shot and killed on October 17, 2013, in the stairwell of his Philadelphia apartment building. Reports say he was struck multiple times—up to 19—and his three-year-old daughter, Aryana, hid in a closet and was left alone with his body for about 30 hours before they were found.

No suspects have been arrested and investigators report no significant leads. The murder devastated Stanley’s family, and his mother described the loss and the trauma endured by his young daughter. Authorities and the family have appealed to the community for any information that could help solve the case.

If anyone knew Armone, saw something in that building on October 17, 2013, or has information that could assist investigators, please come forward.
