Summary based on the NamUs case record (MP37918) and 4 other sources
John Joseph Antinoro, a 24-year-old man, was last seen on August 30, 1988, in Santa Monica, California. He disappeared under unknown circumstances and has not been heard from since. Antinoro was wearing a black leather jacket, jeans, and sneakers at the time of his disappearance. He also had a digital watch on him and wore eyeglasses. Distinctively, he had a pockmarked complexion and two cuts on his head at the time.

Despite extensive efforts to locate him, his case remains unsolved, and very few details about his disappearance have surfaced over the years. Investigators continue to treat his case as an endangered missing person case, and the Santa Monica Police Department remains the primary investigating agency.
