Antonio Delonte Ross was 23 when he was shot to death outside his home in District Heights, Maryland, on the evening of January 18, 2013. Prince George’s County Police found him suffering from gunshot wounds; he was taken to a hospital and pronounced dead. Investigators concluded he had been intentionally targeted.

A silver Chrysler 300 believed to be the suspects’ getaway vehicle was later found abandoned and set on fire in Washington D.C., but that discovery did not produce arrests. By January 2014 detectives were still investigating: officers canvassed the neighborhood, distributed flyers and offered a cash reward for information. The case has since gone cold and no arrests, suspects or convictions have been publicly announced.

If anyone knew Antonio, saw the vehicle, or has information about the shooting, please share what is known with the Prince George’s County Police.
