A man found fatally shot in a St. Louis alley was one of the region's top high school basketball players just three years ago.

The St. Louis Post-Dispatch reports that the body of 21-year-old Tyrin Williams was found Monday afternoon with multiple gunshot wounds. No arrests have been made.

Williams lived in St. Louis County and was a standout guard at Riverview Gardens High School, where he was named Suburban North Conference Player of the Year as a senior in 2013.
