A Casper man is accused of stealing an ATV from the Naval Reserve Oil Field near Midwest and causing more than $1 million worth of damage at a Natrona County mine.

Mark Faulcon has pleaded not guilty to one charge of burglary.

Investigators with the Natrona County Sheriff's Office say in early December 2015, Faulcon along with Devin Williams drove to the oil field, and Faulcon used his employee issued gate access code to gain access.

They cut off a lock from a shed on the field, and took the ATV.

The ATV was later found in a shed on the 2900 block of East 4th Street in Casper, and Faulcon lived in a residence on that property

The rims of the ATV had been spray painted black in an attempt to conceal the true color, but investigators knew it was the one they were looking for based on the vehicle identification number.

When interviewed, Faulcon said he and Williams had entered the shed at the Oil Field to take some tools for personal use, but when they didn’t find what they were look for, they took the ATV instead, even though it didn’t work.

Faulcon is free on $30,000 bond awaiting trial and could face up to 10 years in prison on the burglary charge if convicted.

He is also facing charges in connection to the damage at the mine, and he will have a hearing on that case at a later date.
