Fred Quintero Arechiga, 34, was shot and killed at his San Antonio home on March 4, 1990, after answering a knock at the door. Witnesses heard gunfire and reported a dark-colored vehicle parked in the driveway immediately afterward. He was at home with his three young children when the shooting occurred, leaving them without their father.

The San Antonio Police Department and Crime Stoppers have pursued leads but the case remains unsolved and no arrests have been made. Investigators continue to ask anyone with information about the knock at the door, the dark vehicle, or activity in the neighborhood that night to come forward.

If anyone knew Fred, his movements that evening, or who might have been driving a dark vehicle in that driveway, can you help provide information?
