Diamonic Reyshann Arca-Jones was 19 when he was fatally shot in Parkville, Maryland, on the evening of October 20, 2018. A recent Parkville High School graduate who had been in Junior ROTC, he was found lying in the roadway near Taylor Avenue and Beverly Avenue after police responded about 7:20 p.m. He was transported to a local hospital and died shortly after arrival.

Detectives found no immediate leads and canvassed the neighborhood for witnesses. Months later investigators released surveillance video showing a white car, possibly a Lexus with distinctive rims, leaving the area shortly after the shooting; authorities believe that vehicle or its occupants may be connected to the crime or have witnessed it. No arrests or public identifications of suspects have been made, the motive remains unknown, and a reward has been offered for information.

If anyone knew Diamonic, saw the vehicle that night, or has information that could help the investigation, please come forward.
