"He brought a fare here from the Greyhound bus station and we need to talk to the person who was in the cab to find out what happened, if they saw anything," said Sgt. Kevin Carswell with the Raleigh Police Department.
Detectives released a surveillance picture of the woman, but were careful to say they only want to talk to her. They're not calling her a suspect.
Anyone with information is asked to call the RPD's Detective Division at (919) 996-3555.
