Lonell Boyles was 20 when he was found fatally shot in the backyard of a house near 67th Street and Walrond Avenue in Kansas City. A resident discovered the body and notified police on the afternoon of Tuesday, December 8, 2015; police confirmed Boyles as the victim the next day.

The house where Boyles was found had seen violence earlier that year: a fatal shooting in March in the 6800 block of Walrond Avenue and, in May, a drive-by that killed a 3-year-old, after which that child’s family moved from the residence. Investigators said those earlier incidents were not connected to Boyles’s death. No suspects or arrests were announced at the time, and the homicide remains publicly unresolved.

If anyone knew Lonell Boyles, lived in that neighborhood, or has information about what happened that day, please share what you know.
