Tyshiem Chaney was 17 when he was shot multiple times in the chest on the 5900 block of Larchwood Avenue in Southwest Philadelphia on March 26, 2017. Police found him on the front steps of a home; he was taken to Penn Presbyterian Medical Center and pronounced dead shortly before midnight. Investigators later concluded the shooting occurred during a robbery as Chaney walked with two other young men.

Chaney split time between Philadelphia, where his mother lived, and North Carolina with his grandmother. His grandmother had tried to steer him toward positive activities—volunteering at a food pantry and helping the elderly—and he was described as a talented athlete in basketball and football who enjoyed making music beats. Fired casings at the scene were reportedly matched to a handgun stolen earlier that day and to a 17-year-old, Ma-King Stewart, who was identified by police as involved in a string of violent robberies and non-fatal shootings in West Philadelphia.

Ma-King Stewart was arrested and charged as an adult with murder, robbery and related offenses in Tyshiem’s killing. Chaney’s grandmother went on to found Grandparents Against Street Violence in response to his death. Did anyone in the area know Tyshiem or see activity on Larchwood Avenue that night?
