Who could have guessed that the trail to catching the infamous Golden State Killer led straight through the brilliant mind of a retired attorney, medical doctor and Ph.D. who took on genealogy as a hobby!  But that's exactly what happened when Det. Paul Holes recruited then 69 year-old Barbara Rae-Venter after reading about her phenomenal work two years earlier in San Bernardino.  In this episode Melissa explains in detail how Dr. Rae-Venter used her scientific and deductive skills to help Det. Holes and his team track down GSK - and also hear the story of the amazing case of "Lisa," who, abandoned as a little girl by a convicted serial killer she had thought was her father, finally found a family through the work of Dr. Rae-Venter, a dogged police detective and a whole lot of good people who volunteered to help.
