The Zanesville Fire Department says a 12 foot camper was destroyed in a fire Friday morning. Chief Eric Waltemire says it happened just before 8:30 at 831 Alfred Street. The chief says when his crew arrived on the scene the camper was fully engulfed in flames and billowing smoke. The video that is part of this story was shot with a cell phone by a passerby. Chief Waltemire says the camper was being used as a residence by Eric Kessler, however no one was home at the time of the incident. Chief Waltemire says the cause of the fire is unknown at this time, but a propane heater had been in use in the camper and it is possible that was the cause. No injuries were reported.
