On the night of August 11, 2017, 25-year-old Andrea Gardner was at a bonfire gathering near Harry Laker Park on Central Avenue in Detroit when at least 30 shots rang out. Witnesses described the attack as an ambush: an unknown assailant approached the group of about eight people and opened fire. Gardner was struck in the head and died at the scene.

A 25-year-old man at the party was also hit and later died at a nearby hospital. Witnesses said they saw a black Charger speed away immediately after the shooting, and some reports suggested an AK-47 may have been used, but the shooter’s identity was not established.

Who knew Andrea or the others at that bonfire and might have information about the black Charger or anyone seen approaching the group that night?
