Area firefighters suspect they may be dealing with a serial arsonist who is targeting abandoned buildings. Corbin, Oak Grove and Woodbine Fire departments have been called to four such fires this week. The Departments, as well as Whitley EMS, were called out to separate incidents on Gordon Hill, Fairview Street, Vine View Drive and Ky. 1064. While arson has not been confirmed in any of the fires, the nature and timing has firefighters suspicious. Again, the buildings were empty, some abandoned for some time with no electricity. Anyone with information about any of the fires is asked to contact Whitley County dispatch at 549-6017 or Corbin dispatch at 528-1122. Callers may remain anonymous.
