David M. Sutton, Jr., a 36-year-old antique store owner in Everett, Washington, was found in his shop on January 27, 1980, with a fatal gunshot wound to the head. The scene was also a robbery: $80,000 in silver dollars was taken from the business. The violent attack left no immediate suspect and the case went cold for a decade.

In August 1990 investigators identified Charles T. Sinclair as a prime suspect. Sinclair was in custody in Alaska for other coin shop murders and investigators tied him to a pattern of befriending coin and coin shop owners, learning routines, then robbing and killing them. Sutton is reported as one of at least eleven victims linked to Sinclair. Detectives planned to question Sinclair about Sutton’s death, but Sinclair died in custody in October 1990 before that interview could occur, leaving some questions unresolved.

Does anyone have memories of Sutton, his shop, or information from the months before January 1980 that could shed light on his final days?
