Mario Peanut Marks Jr., 18, was shot and killed in Louisville’s Newburg neighborhood on September 1, 2021. Police found him inside a car at the intersection of Jefferson Boulevard and Poplar Level Road around 4:30 p.m.; he was taken to the University of Louisville Hospital and later died of multiple gunshot wounds.

A witness at the scene identified 21-year-old Derrick Stover as the shooter, saying Stover fired several shots from the backseat before fleeing. Surveillance footage showed a man running toward Corinth Way, and a police helicopter later spotted Stover in a yard as he attempted to leave in an Uber. Stover’s grandmother told detectives he ran into the back of her house claiming he’d been in a shootout, and investigators were told he discarded his clothes and the handgun there.

Stover was arrested and charged with murder, tampering with physical evidence, and wanton endangerment. If anyone knew Mario or saw activity around Jefferson Boulevard and Poplar Level Road that afternoon, please share what was observed.
