Please see the attached document for instruction. And I would like to write the paper about this killer, Timothy Wilson Spencer. Timothy Wilson Spencer (March 17, 1962 â€“ April 27, 1994), also known as the â€œSouthside Stranglerâ€œ, was an American serial killer who committed three rapes and murders in Richmond, Virginia and one in Arlington, Virginiain the fall of 1987. In addition, he is believed to have committed at least one previous murder, in 1984, for which a different man, David Vasquez, was wrongfully convicted. Spencer grew up in one of the toughest black neighborhoods in Arlington, called Green Valley. He was known to police as a prolific home burglar. Spencer became the first murderer in the United States to be convicted on the basis of DNA evidence, with David Vasquez being the first to be exonerated following conviction on the basis of contradictory DNA evidence.
