Billy Elmore was 71 when he disappeared from Ephrata, Washington on April 30, 1997. The last things his wife found were two contradictory notes. One said he had gone on a short trip to look for something and would report back; the other said he had found it, would not be back to pick anything up, and that the visit was over.

About a year later a blue 1990 Dodge pickup registered to Billy was found abandoned in a storage unit; how it got there and who placed it there are unknown. Investigators also located a boat believed to belong to Billy on Lake Pend Oreille in Idaho. The hull was damaged and the boat’s accelerator had been tied down, indicating it had been sent across the water unmanned.

Those clues—opposite notes, the abandoned truck, and the damaged boat—leave the case unresolved. If anyone knew Billy’s movements around April 30, 1997, or has information about the truck or the boat, please come forward.
