Charles Brown, 40, was shot during what was arranged as a gun purchase in the Carondelet neighborhood of St. Louis. On the afternoon of December 18, Brown went to an alley to complete the transaction. He was met by two people in black clothing and ski masks; after Brown handed over money, a third person with the group shot him in the abdomen.

Officers arrived about 2:40 p.m.; Brown described his assailants before being taken to a hospital. He died of his injuries on December 30. Investigators later arrested 20-year-old Juan D. Harris of the 300 block of Krauss Street and charged him with first-degree murder and armed criminal action. Court papers name Harris and another, unnamed individual as meeting Brown for the sale; it is not publicly known whether the third person who fired has been identified or taken into custody.

Does anyone have information about the meeting location in Carondelet or the people seen in the area that afternoon?
