Robert McDonald was 22 when he disappeared from Sunset, Hawaii, in late spring 1976. On May 20 he told his roommate he was driving to visit a friend in Kahuku and left his Kanalani Place home in a maroon 1970 Toyota pickup. He wore a white t-shirt, green shorts, yellow slippers and a Seiko watch with a black face and gold band.

McDonald’s pickup was found abandoned in the Swanzy Beach Park parking lot on May 25, and no one has reported seeing or hearing from him since May 20. Rumors circulated that he might have been murdered by two acquaintances over a drug dispute, and his parents hired a private investigator who suggested he may have been traveling to collect a $1,500 debt. The Honolulu Police Department continues to list him as an endangered missing person and no charges have been filed.

Does anyone remember seeing Robert, his maroon pickup, or anyone acting suspiciously near Swanzy Beach Park around May 20–25, 1976?
