Timothy Wilson Spencer has the distinction of being the first American serial killer to be convicted on the basis of DNA evidence—evidence that also exonerated a man who had been in prison after being wrongly convicted of committing one of Spencer’s murders. A troubled adolescent from Arlington, Virginia, with a deep hatred of women, Spencer utilized his cat-burglar skills, strength, and agility to gain entry into his victims’ homes, lay wait, and then bind, rape, torture, and murder them. In total, Spencer had been linked to five murders and at least nine rapes in both Richmond and Arlington, Virginia. He was convicted of the murders of four of his victims and sentenced to death. Spencer was ultimately executed in the electric chair on 27 April 1994.
