Casey Ross, 24, was found dead from a gunshot wound near the intersection of North 15th and Mullanphy streets in Saint-Louis, Missouri. The body was discovered on Sunday, September 19, 2021. Ross’s death was one of several linked shootings that alarmed the community that fall.

Investigators determined ballistic evidence tied the same firearm to six homicides, including Ross’s, and noted a pattern in many of the victims of wounds to the head and an arm or hand. Witnesses described a suspect with a crescent moon-shaped tattoo on the forehead, a detail officers used while pursuing leads.

Does anyone have information about Ross, his movements that day, or sightings near North 15th and Mullanphy in September 2021?
