Jack Charles O’Hollaren was a 20-year-old University of Oregon sophomore who disappeared on the evening of April 15, 2016, near the Siuslaw River north jetty in Florence, Oregon. He was described as a white male, black hair, brown eyes, about 5 feet 10 inches and 120 pounds. Witnesses said he had been at a beach party and was under the influence of alcohol and drugs before entering cold water shortly after 8:00 p.m.

Observers reported he swam roughly 40 yards from shore into water estimated at about 54 degrees Fahrenheit, was seen disappearing into the surf, and did not return. An extensive multiagency search followed, including Coast Guard boats and helicopters and searches covering roughly 100 square miles, but nothing was found and the operation was eventually suspended. Authorities have continued to treat his case as a missing-person investigation and have noted the possibility he drowned, though no remains were recovered.

If anyone was at the north jetty or the beach party that night or has information about Jack’s movements that evening, please share what is known with investigators.
