Khris Mckinney was 17 when he was shot at Norfolk and Whitman streets in Dorchester around 3:10 p.m. on March 24, 2011. He died at the scene.

Police were looking for two Black men seen leaving in a red truck with New York plates. A red truck with out-of-state plates in Dorchester in the middle of the afternoon is the kind of thing people notice.

Boston police still list Khris's case as unsolved. If you remember that truck or know who was in it, the Boston police anonymous tip line is 1-800-494-TIPS, or text TIP to CRIME (27463).
