Damon A. Dawson was 23 when he was shot and killed on April 19, 2016, while taking part in a music-video shoot in Foster Park on Chicago’s South Side. The video was for a song about guns titled Two Techs and a 50 Shot. An unidentified gunman walked up to the group and opened fire; Dawson was struck fatally and four others were wounded. Dawson was pronounced dead at the scene.

Authorities have said the shooting may have been gang-related, but no definitive motive had been determined. Dawson’s family had warned him about dangers in the area.

If anyone knew Dawson, was at Foster Park that day, or has information about the shooting, please come forward.
