John Warner Nolen was a 45-year-old former Tacoma, Washington police officer whose body was recovered from the Columbia River at Kelley Point, near the mouth of the Willamette River, on April 29, 1992. Investigators estimated the body had been in the water about seven to ten days. The medical examiner determined the cause of death was a gunshot wound, but the manner of death remained officially undetermined between suicide and homicide; investigators said unusual circumstances made homicide the more likely explanation.

Nolen had been missing from the Tacoma area since about March 1992, and a family member did not report him missing until April 1993. The body in Oregon was unidentified until 2013, when dental records confirmed it was Nolen. The Multnomah County Sheriff’s Office lists the case as cold case 92-3882 and in 2024 included it among long-unsolved deaths on a new cold-case webpage. No suspect, arrest, charge, or conviction has been publicly reported.

Does anyone have information about Nolen’s disappearance or his movements in March–April 1992 that could help investigators?
