PIKEVILLE - A Knott County resident has been arrested for cultivation of marijuana by the U.S. Drug Enforcement Administration after videotape surveillance allegedly captured the accused tending to his crop. According to the criminal complaint filed by special agent David D. Gray, of the U.S. Drug Enforcement Administration, Gray received information from the Kentucky State Police that Knott County residents Ardith Dobson and others were distributing and manufacturing marijuana. KSP Lt. Ed Sheymleya and Det. Tim Ingles placed two surveillance cameras on several plots of marijuana located on property owned by Ardith Dobson. Although the cameras were in operation over a period which spanned nearly two months, no activity was recorded the first few weeks. Approximately five weeks into the surveillance on June 4, a white male positively identified as Ardith Dobson could allegedly be seen on the video weeding and loosening the dirt around the marijuana plants. On June 21, investigators traveled to the crop in Knott County and when they arrived at the location they intercepted Ardith Dobson at the intersection of Dobson Cemetery Road and Buckhorn Road. Ardith allegedly said that he and his father were the only people who had keys to the locked gate leading to the cemetery where investigators had been entering the marijuana plot. Ardith Dobson said he had been hearing four-wheelers in the area. When they asked for the keys to the gate, Dobson said he has lost them and consented for the locks to be cut by investigators. When the surveillance cameras were checked, investigators once again positively identified Ardith Dobson as the subject who was caught tending to the marijuana crop. The crop was removed and disposed of by the investigators which included nearly 80 marijuana plants. Dobson was arrested on August 6 and is scheduled to appear in U.S. District Court for a preliminary hearing on Tuesday.
