Prosecutors say a drug deal gone wrong was the motive for a shooting in Graves County last week that left two dead and one injured. At a preliminary hearing yesterday, Graves County Sheriff’s Detective Brad Smith testified that witnesses said Ashley Lambert of Dublin took money from Jacob Carder and Kenon Andrews to purchase methamphetamine for them. A week later, Lambert had neither the drugs nor the money, so Carder and Andrews confronted her. The incident left 25-year old Lambert, 22-year old Jonathon Cagle, and 18-year old Whitley Moore shot in the head. Only Moore survived.
