WASHINGTON — Montgomery County police said the two people found dead in a running car in Burtonsville last month may have known their killer.

On the evening of Feb. 16, the bodies of 34-year-old Ashley Susan Dickinson, of Alexandria, Virginia, and 29-year-old Joshua Michael Frazier, of Woodbridge, Virginia, were found in a running car parked in a town house parking lot in Burtonsville, Maryland. Both died from gunshot wounds, according to police.

Detectives are investigating their deaths as homicides and said they believe there was “some prior association” between the victims and suspects.

“These murders were not random,” police said Tuesday.

Anyone with information on the case can contact police at 240-773-5070.
