A suspect has been arrested on charges stemming from a fatal confrontation Friday morning, and detectives are calling it a case of road rage.
Gloria Alfreda McMillan, 32, of 7238 John Paul Drive in Alexandria, has been charged with felony hit and run.
Shelinda Delores Arrington, 21, died in the incident.
Detectives have seized the suspect's vehicle, a 2006 black Chevrolet Trailblazer, from Southwest D.C.
A witness had described the vehicle that struck Arrington as a dark SUV. That witness didn't want to show his face or give his name, but he spoke to News4's Darcy Spencer on Monday.
"The [driver of the] truck hit his gas, hit her; she flew into the air," said the witness. "She flew maybe about... 20 feet from where her car was."
The witness said he saw the victim pull out of an apartment complex on Harrison Lane at Robert E. Lee Place, cutting off two SUVs.
Arrington was on her way to the hospital to see her mother, who was recovering from a stroke.
The witness said Arrington stopped and got out of her car. Police say Arrington was seen arguing with the driver of one of the SUVs before she was run over.
The witness heard the other driver rev the engine. He said he believes the impact was intentional because the driver had come to a complete stop before hitting her.
"I don't know how I'm going to get through this," said Arrington's mother, Tonya Moore.
Arrington, her only child, was a college student who was studying criminal justice.
