Cynthia Kirk, age 34, was fatally stabbed outside her Durham, North Carolina, home on August 21, 1989. She was preparing to leave for work and loading her car while her 2-year-old daughter slept inside when she was attacked in her driveway and collapsed near the door to the house on Constitution Drive, a quiet neighborhood near Duke University.

Investigators say a witness reported seeing a middle-aged white man driving a green sedan near the scene around the time of the murder. Police ruled out her husband as a suspect, but with very little physical evidence and no clear motive, no arrests have been announced and the case remains unsolved. CrimeStoppers is offering rewards for information that could lead to an arrest.

If anyone knew Cynthia, saw a green sedan in that neighborhood on August 21, 1989, or has information that could help bring justice, please come forward.
