Summary based on the NamUs case record (MP74357) and 4 other sources
In the early morning hours of November 16, 2018, 39-year-old Billy Joe Darwin vanished from his home in Custer, Washington. He was last seen at his residence at approximately 1:00 a.m. and was discovered to be missing just a few hours later, around 4:30 a.m. The circumstances surrounding his disappearance were immediately concerning. Several of his personal belongings, including his keys, beanie, and cell phone, were found outside his home. A particularly puzzling detail was that although it had rained during the night, the beanie that was found was dry. Adding to the mystery, his car was discovered parked sideways in the driveway. At the time he went missing, Billy was described as being 5'10' tall and weighing between 120 and 130 pounds, with brown hair and hazel eyes. He was believed to be wearing a royal blue sweatshirt with a dark yellow logo, dark gray pants, a brown coat, and black lace-up Vans shoes.

The investigation into Billy's disappearance began promptly, with the Whatcom County Sheriff's Office taking the lead. Despite efforts by law enforcement and concerned family members, who organized a search party in the days following his disappearance, there have been no signs of Billy. His bank accounts have remained untouched since the day he went missing, suggesting a sudden and unplanned departure. Authorities have noted that while Billy was a known drug user, he had no history of disappearing for extended periods, and he did not communicate any plans to leave to his family. There was some speculation that he may have taken his sister's bicycle. His case is listed in the National Missing and Unidentified Persons System under case number MP74357.

Billy has several distinct physical features that could aid in his identification. He has an approximately 3-inch horizontal scar on his left thigh. He also has two tattoos: a small, quarter-inch peace sign between his thumb and finger, and a faint, incomplete capital 'B' on the backside of his left shoulder that resembles the letter 'P'. The Whatcom County Sheriff's Office continues to seek information from the public regarding Billy's whereabouts. The case remains a painful and unresolved mystery for his family and community, who are left to wonder what happened in the predawn hours of that November morning. The strange positioning of his car, coupled with the dry beanie amidst the rain-soaked surroundings and the untouched personal effects, paints a confusing picture of his last known moments.
