A violent exchange of gunfire on Interstate 94 left 19-year-old Alvin Lil Mark Johnson of Saint Clair Shores dead. The African American passenger, a former Harper Woods High School offensive lineman, was shot during an apparent gunfight between occupants of two vehicles about 1 p.m. on April 26, 2025 near 10 Mile Road. The black Chevrolet Malibu carrying Johnson collided with a GMC Acadia and pulled to the shoulder; the opposing silver vehicle fled eastbound at high speed.

Witnesses saw a Malibu passenger carry a pistol up an embankment and discard it; investigators recovered a 9 mm Glock 19 modified with a switch in the area. Two people from the Malibu, including Johnson, were taken to a hospital, and Johnson later died. The freeway was closed for hours while Michigan State Police investigated. No suspects have been publicly identified and no arrests have been announced.

If anyone saw the vehicles, the shooting, or the person discarding the gun, can you share what you know with investigators?
