Vernon Parker

Vernon Parker has been identified as the lead suspect in the January 15, 1981 rape and murder of 17-year-old Mary London in Sacramento, California.

London was developmentally disabled, and she disappeared on her way to her scheduled ride for school. Her body was found near I-5 the next day. She was nude and had been stabbed multiple times.
