A Fourth of July block party on Cherrylawn Street on Detroit’s west side ended in tragedy shortly after midnight on July 5. Jordan Thornhill, 23, a recent Michigan State University graduate, was fatally shot at about 12:50 a.m. He had been at the party with friends and fraternity brothers when gunfire erupted and chaos followed.

Jordan’s younger brother Chandler was on the phone with him when the shots rang out and later found him fatally wounded. Friends at the scene described trying to flee as multiple firearms were discharged; investigators believe the fatal wound may have resulted from celebratory gunfire. The Detroit Police Department is investigating, no arrests have been announced, and a $25,000 reward is being offered for information leading to an arrest. Jordan’s father Andre Thornhill and the family have publicly appealed for witnesses to come forward.

If anyone was at that block party or has dashcam or phone video from the area that night, can you share what you saw with investigators?
