Louis Carl Muller, known as Buck or Bucky, was 62 when he was last seen in Elma, Washington, on October 21, 2012. He and his wife co-owned an antiques store. He told his wife he planned to travel to South Dakota the next day and she later said he packed and left as planned, yet his vehicle, cellphone and his dog were left at home and there has been no bank activity since his disappearance.

Two days after he was last seen, on October 23, 2012, his wife filed a complaint against him for fourth-degree domestic violence assault that led to a warrant for his arrest; it is unknown whether he ever learned of the complaint or warrant. An official investigation did not begin until months later when the Grays Harbor County Sheriff’s Office received an anonymous letter urging them to look into his whereabouts.

Muller is described as a white male, brown hair, blue eyes, about 5 feet 11 inches and 235 pounds, with a tattoo on his left shoulder and a missing finger or part of a finger on his left hand. He requires insulin for diabetes and has diagnoses of severe depression and intermittent explosive disorder. Does anyone who knew Louis, his routines, or travel plans in October 2012 have information that could help explain what happened?
