Utilities have been battling copper theft for a number of years.
Copper theft became a serious problem in 2006 when the price of copper increased.

A Boone County man was electrocuted in April when he grabbed a 7,200-volt power line he thought was made with copper, but instead was Copperweld, a compound with a copper surface but with a core made from less expensive materials.
Appalachian Power spends about $1 million a year to replace stolen copper wire.
The investigation remains underway.
Garren was conducting interviews Sunday with associates of Marcum. Troopers received information that Marcum was not alone on the hilltop Wednesday.
