Jefferson County Sheriff’s investigators are looking into a second major copper theft in recent weeks at Hamm Quarry north of Lawrence.

Sheriff Jeff Herrig said officers believe the quarry was burglarized either late Saturday night or early Sunday morning. The incident is under investigation. Investigators suspect several hundred feet of copper wire was stolen from a conveyor belt at the landfill and quarry, which is just north of U.S. Highway 24-59.

Officers arrested an Oskaloosa man in December after a similar theft of 500 to 600 feet of wire from the conveyor belt.

Herrig said investigators believe more wire was taken during last weekend’s burglary than the one in December. He said an old pickup truck with Hamm insignia on the side was also stolen.

It’s suspected the truck was used to transport the copper wire.

Herrig asked anyone with information in the case to call the sheriff’s office at 785-863-2351.
