Investigator Brandon Heath Thacker, 27, was shot and killed on the evening of Thursday, April 16, 1998, while traveling to an undercover assignment along the Western Kentucky Parkway near Eddyville. A four-year agent with the Kentucky Department of Alcoholic Beverage Control and a U.S. Army Persian Gulf War veteran, Thacker was riding in the last car of a caravan of unmarked vehicles when he radioed colleagues to report an erratically driven vehicle. Moments later he radioed that he had been shot; his car swerved and an agent ahead turned back to render aid.

One agent stayed with the mortally wounded Thacker while two others pursued and stopped the erratic vehicle, apprehending the driver. Thacker died of a single gunshot wound from a .44 caliber handgun. The suspect was arrested, convicted of manslaughter and sentenced to 20 years in prison. Thacker was survived by his wife, their 18-month-old daughter, his parents and two brothers and was buried in Richmond Cemetery in Richmond, Madison County, Kentucky.

Did anyone on the Western Kentucky Parkway that night see the erratic vehicle or the caravan before the shooting?
