LACKEY - Kentucky State Police are now searching for perpetrators of three unsolved robberies. The latest robbery took place Friday night at the Mi-Dee Mart in Lackey, where a white male entered the store at approximately 10:40 p.m. and assaulted the clerk before leaving with an undisclosed amount of cash. KSP reported that the man asked the clerk for an item off the bottom shelf behind the counter and that the man struck the woman with an object believed to be a crowbar or a tire iron. The man then ordered the clerk to "hand over the store's money," KSP reported. The clerk later refused medical treatment. The man's direction and mode of travel were not ascertained by those at the scene. He is described as being approximately 20 years old and was wearing a white baseball cap, blue long-sleeve shirt, black t-shirt and khaki shorts. Trooper Austin Hicks continues this investigation, which mirrors an unsolved robbery that took place at Tackett's Grocery in Galveston on June 29. KSP reported that an unidentified armed robber entered the store, hit the clerk, store owner Brenda Tackett, in the head with a hard object and knocked her unconscious before fleeing with an undetermined amount of cash. Tackett woke up on the floor behind the register and a female customer helped her get back up. Det. Byron Hansford continues this investigation. Det. Rick Conn is also continuing the investigation into the robbery that occurred on June 28 at Citizens National Bank in Allen. A white male, described as being between 5 feet, 10 inches and 6 feet tall, entered the bank early that morning with a canvas bag over his head. He left with an undisclosed amount of cash. Investigators at the scene said the man "hunkered" below the counter and "bobbed" his head above the counter during the robbery. He was captured on video only briefly, officials said. No weapon was seen during the robbery, but the man threatened the teller with a firearm. KSP information officer Scott Hopkins said Tuesday that no arrests have been made in any of these robberies. Hopkins said the robberies at the two stores sound similar, but he would not speculate as to whether the robberies are connected. Hopkins urged the community to contact authorities if they have any information about these incidents. Anyone with information can contact the Kentucky State Police at (606) 433-7711 or (800) 222-5555. Callers may remain anonymous.
