Police said Gloria A. McMillan of Jon Paul Drive was charged with felony hit-and-run in the incident, in which Shelinda Delores Arrington, 21, was found lying fatally injured Friday morning on Harrison Lane. Arrington apparently had left her vehicle. Her death was ruled the result of a crush injury.
After Arrington was found, police put out a lookout for a dark-colored sport-utility vehicle with temporary tags. County police said they found such a vehicle in Southwest Washington with the aid of D.C. police.
Officer Don Gotthardt, a county police spokesman, said McMillan surrendered about 7:30 p.m. Monday at the Mount Vernon district police station.
Since Friday, police have said they were trying to determine whether Arrington knew the other driver in the incident or whether road rage was involved.
Police are continuing to investigate, Gotthardt said, and believe that even though the two women lived only a few blocks apart, they did not know each other.
“We have been able to speak with witnesses,” he said, as well as the suspect, and “based on all the information we gathered,” police were “confident” that it was a road-rage incident.
From what police have learned, Gotthardt said, it appeared that an interaction began between the women while both were driving. A verbal altercation broke out and matters escalated, Gotthardt said.
“It’s a tragedy,” he said. In any such incident, he recommended, “never get out of your vehicle.”
