David Cruz was 29 when he was last seen in Allentown, Pennsylvania, on October 31, 1980. He is described as a Hispanic male of Puerto Rican descent, 5 feet 9 inches tall, about 160 pounds, with brown hair and brown eyes and a tattoo on his lower left arm.

He was not reported missing until November 7, a week after his last sighting. It is believed he may have been heading to meet one or more people to collect a debt, a detail that prompted the Allentown Police Department to classify him as an endangered missing person under suspicious circumstances. Few solid leads emerged and the case grew cold.

If anyone knew David, saw him around Halloween 1980, or has information about people he might have been meeting, please come forward.
