Arthur Robinson was found dead behind the greenhouse where he had been living in Searsmont, Maine, on January 1, 1980. Authorities determined the circumstances pointed to foul play, and the Maine State Police opened a homicide investigation.

Investigators considered robbery as a possible motive and have interviewed numerous people over the decades, but no arrest has been made. The case remains an unsolved homicide and is cold, though authorities continue to seek information that could identify who was responsible.

If anyone knew Arthur, his routines, or observed anything unusual in Searsmont around New Year’s 1980, please share what was seen or remembered.
