Gregory Jones Credit: Via Montgomery County police

Montgomery County police arrested a West Virginia man Monday and charged him with the killing of two people in Burtonsville last month.

Gregory Terrell Jones, 24, allegedly owed one of the victims money for heroin, according to police. He was arrested after his gun was fired at the scene of another fatal shooting in West Virginia.

Virginia residents Ashley Susan Dickinson, a 34-year-old from Alexandria, and Joshua Michael Frazier, a 29-year-old from Woodbridge, were found shot to death Feb. 15 in a running car parked on a residential street in Burtonsville.

A resident had walked by the white Audi Q7 on Aldora Circle at about 10 p.m. and called 911. Police found Dickinson in the driver’s seat and Frazier in the front passenger seat. Both were declared dead on the scene.

Detectives investigated the deaths as a double homicide and eventually determined from tips and forensic evidence that two West Virginia cousins were involved: Jones, from Martinsburg, and Tyshon Jones, a 25-year-old from Bunker Hill, who was also known as Lamar Green, according to police. Police wrote in a press release that Frazier had come to Burtonsville to collect money Gregory Jones “owed him from a previous drug (heroin) transaction.”

Two days after the Burtonsville homicides, on Feb. 17, Tyshon Jones, the older cousin, was also killed in a shooting. He died after gunfire broke out at the Coco Loco nightclub in Berkeley County, West Virginia, according to police.

At the nightclub, local police recovered a .45-caliber handgun that belonged to Tyshon Jones, according to police. Another handgun, a 9mm, had been fired at the scene, and the shooter had fled. Police in Montgomery and Berkeley counties, as well as investigators with the Bureau of Alcohol, Tobacco, Firearms and Explosives, identified that shooter as Gregory Jones and determined the 9mm shell casing recovered at the nightclub was fired from the same gun used in the Burtonsville homicides, police said.

Montgomery County police arrested Jones in Gaithersburg. He is currently being held without bond, according to police.
