ARLINGTON — The man who was reportedly the last person to see Granite Falls woman Angela Gilbert before she disappeared in June has died.

Colt White’s body was recovered from the Stillaguamish River on July 24. It is unknown how long the body was in the river, but decomposition suggests it was weeks, as opposed to days.

The Snohomish County Medical Examiner’s Office conducted an autopsy on White, but the cause and manner of his death are pending. At this time, detectives are referring to the case as a death investigation, since cause and manner of death are unknown.

The 23-year-old Granite Falls man was friends with Angela Gilbert. A third party reported that Colt White and Angela Gilbert went for a walk on some private timber land near Granite Falls on June 2 and that White returned alone, saying that Gilbert had decided to continue walking by herself. Gilbert has not been seen or heard from since.

White was reported missing a few days later by a family member. However, there are some reports that he had been spotted in the community after being reported missing. Detectives did not see him, and they never had the opportunity to speak to him about Gilbert.

Anyone with information about Colt White’s death or Angela Gilbert’s disappearance should call the Sheriff’s Office tip line at 425-388-3845.
