Darrel Smith’s body was found inside the woodshop next to his home two weeks ago.
State police detectives say he had been shot to death and robbery may have been the motive.
Smith’s wallet and a safe have not been located since his death.
Detectives are asking for help from the public in piecing together more information.
They’re also looking for the driver of a small, dark-colored pickup that was spotted near smith’s home on the day of the killing.
The vehicle had its hazard lights on and the hood up, indicating possible mechanical trouble.
