Nine years after Susan Powell vanished from her West Valley City, Utah home, more than a terabyte of data from her husband and his father's digital devices remains encrypted -- and therefore unknown to police. But much of what we do know about the case from the top-rated podcast, Cold, comes from data seized from those machines. The FBI has 16 Regional Computer Forensics Labs around the country, and one of them, led by Supervisory Special Agent Cheney Eng-Tow, is in Salt Lake City. From the early days of the Susan Powell investigation, the FBI's Intermountain West RCFL assisted West Valley police in working to uncover what Josh Powell was hiding. Investigative reporter Dave Cawley joins Becky Bruce with a sneak peek at what he's working on in Cold.
