Avion J Polk was 22 when he was shot dead in St. Louis on April 23, 2015. Police were called about 11:15 p.m. to the intersection of Vandeventer and Evans avenues and found Polk deceased with multiple gunshot wounds to his head, torso, and hands.

Witnesses said a heated argument preceded the shooting. Occupants of a dark-colored Pontiac Grand Prix reportedly pulled up alongside Polk, shots were fired from the vehicle, and the suspects fled in the Grand Prix. Police opened a homicide investigation but obtained no immediate leads on the shooters or a motive.

The case remains an open homicide; the people in the Pontiac have not been publicly identified and no charges have been announced. If anyone has information about that night, the community’s tips could be crucial in moving this investigation forward.
