The March theft of a safe from the Del Norte Solid Waste Management Authority's office remains under investigation.
The safe contained an unspecified amount of cash up to $5,000, said sheriff's Commander Bill Steven.
The suspect cut through a wall of the prefabricated building where the safe was located, Steven said.
Video surveillance showed a dark figure that was unidentifiable, Steven said.
"They used a hand cart to carry the safe away down a trail (near State and Benson streets)," said Steven.
The theft is not suspected to be an inside job since there was a report of a break-in at the office in February when the burglar was unsuccessful in taking the safe, Steven said.
