Police believe that before a woman was struck by a vehicle and killed early Wednesday morning, she and the driver of the vehicle got into an argument.
Witnesses to the crash told police that 62-year-old Mary Piette got out of her car shortly before 1:30 a.m. on the North Interstate 35 service road near 53rd Street. Witnesses said she was verbally confronting the male driver of the other vehicle. They said the man got out of the car along with at least two other passengers and "verbally engaged the victim."
Eventually, the people in the other car got back in before running over Piette. They then drove off. Their vehicle has been described as a blue, four-door sedan. The driver is described as a white male. A full suspect description has not been released yet.
The Travis County Medical Examiner ruled Piette's death a homicide.
Police are reviewing surveillance video from the area and investigating what led up to the fight and whether or not Piette knew the people in the other vehicle.
APD is asking anyone who knew Piette to contact them.
"We don't know why she was out at 1:30 in the morning on a Wednesday," APD Lt. Justin Newsom said. "That could be part of her normal behavior, her normal patterns, but that's the kind of stuff we need to know and don't."
Detectives are asking anyone with any information regarding this incident or about Piette to call the Homicide Tip Line at 512-477-3588 or Crime Stoppers at 512-472-TIPS or text "Tip 103" plus your message to CRIMES.
