Police are working to identify the victim and locate a suspect, who may have been driving a black Toyota found near the scene.
A black Toyota Camry found near the scene of a fatal hit-and-run in Herndon is registered to the victim's husband, authorities said.
Police were called to a parking lot in the 600 block of Center Street just after midnight Wednesday.
"At the scene they found a woman who had been struck by a vehicle," Herndon police Lt. Ron Thunman said. "They summoned rescue units. She was pronounced dead at the scene."
Police found three young children left alone at the victim's home. The children were in good health and were turned over to Child Protective Services.
The Toyota found near the scene had apparently hit several other parked cars. The occupant or occupants had fled by the time police arrived.
Police are looking for the victim's husband, 32-year-old Fitsum Abrha Gebretatios. He's described as a black man standing 5-foot-10, weighing 170 pounds with black hair and black eyes.
About 5:30 p.m. Wednesday, officers found the body of an unidentified male in a creek that runs parallel to Center Street.
Authorities have not yet determined if the Toyota was also involved in the fatal accident. They are asking anyone with information to call the Herndon Police Department at 703-435-6846.
