Colonial Parkway Killer is the name given to an apparent serial killer believed to have murdered at least eight people along the Colonial Parkway of the U.S. Commonwealth of Virginia (or nearby) between 1986 and 1989. During that time, three couples were murdered and one couple is missing and presumed to be dead. The first two known victims were Cathleen Thomas, 27, and Rebecca Ann Dowski, 21. The lesbian couple liked to park on the Colonial Parkway for privacy. On October 12, 1986, their bodies were found inside Thomas' Honda Civic, which had been pushed down an embankment near an area of the parkway that was popular with gay couples. An autopsy found rope burns on their necks and wrists, signs of strangulation, and their throats had been slashed. Their purses and money were found inside the car. It appears that Thomas may have struggled with her attacker. A clump of the suspect's hair was later captured by her fingers.
