Stephen Douglas Penta is listed in NamUs as a 26-year-old white man last seen in Santa Cruz, California, on August 1, 1975. He is described as about 6 feet tall, about 185 pounds, with red or auburn hair; his eye color is listed as unknown.

Did anyone in Santa Cruz or Toronto in 1975 remember seeing Stephen Penta or have information about his movements that August?
