Police knew Fred Klenner was dangerous when they spotted his van on the outskirts of Greensboro, North Carolina, on June 3, 1985. A month earlier, he had slaughtered a family of three at Winston-Salem, and he was also sought in connection with the 1984 murders of a mother and daughter in Prospect, Kentucky. Authorities were ready to subdue him in the case of physical resistance, but they never got the chance. When Klenner's van was stopped, he opened fire with a machine gun, wounding three officers in the initial burst of fire. Before they could respond in kind, he threw a switch and detonated an explosive charge inside the van, killing himself and his three passengers. Identified as 39-year-old Susie Lynch and her two sons, the latest dead were related by blood or marriage to all of Klenner's previous victims .
