31-year-old Elizabeth Sullivan was reported missing in 2014. Her body is found two years later in the San Diego Bay. Where has she been in the meantime? Investigators conduct a thorough search of her home. Forensic tests find Elizabeth Sullivan’s blood soaked into the wooden floor in her bedroom and the carpeting.  A major clue however, a police cadaver dog reacts to a spot in the Sullivan garage where a refrigerator-freezer stood for several years. Joe Scot Morgan, Professor of Forensics at Jacksonville State University, and former death scene investigator explains how this discovery impacted the investigation.
