Dennis Nolan, a 44-year-old white man, was found dead on April 29, 2013, off the side of a trail near Pupukea Road on the North Shore of Oahu. Investigators reported multiple stab wounds, indicating he had been attacked at close range. Authorities have not publicly explained what brought him to that remote stretch of road or the events immediately before his death.

The location—a secluded trailhead surrounded by thick forest and some distance from the main highway and nearby homes—meant there were likely few potential witnesses and sounds could be muffled by the trees. The Honolulu Police Department’s Criminal Investigation Division treated the death as a homicide and the case was later listed among the department’s cold cases; detectives appealed to the public and directed tips to CrimeStoppers.

If anyone remembers seeing someone or something unusual near Pupukea Road around April 29, 2013, please share what you know with investigators or CrimeStoppers.
