Ted Bundy seemed to be a friendly young law student. But behind his pleasant façade lurked a demonic psychopath who preyed on young girls.

At 7.18 a.m. on the morning of 24 January 1989, an executioner hired by the state of Florida flipped a switch and sent a 2,000-volt surge of electricity coursing through the body of Ted Bundy. For 60 seconds the mass killer arched and twisted against the straps that held him, as if fighting death. Then, as the power was switched off, he sank back, his life extinguished. ‘Old Sparky’, the oldest electric chair in America, had done its duty once again.
