Missing in America

During his time with the Anne Arundel County State Attorney’s Office, Dave Cordle worked on many cases. The chief investigator has now been retired for more than a decade, but there are three cases he can’t forget: the murder of Donna Lee Dustin, the death of Elizabeth Greenberg, and the disappearance of Nancy Snow. Cordle talks with Josh Mankiewicz about the Nancy Snow case in Season 4 of Dateline: Missing in America.

Lisa Valentino has been waiting for answers—and justice—for nearly 20 years. In 2006, her sister, Allison Jackson Foy, vanished from Wilmington, North Carolina. Her remains were found in 2008. Lisa credits a lot of the help she’s gotten over the years to the CUE Center for Missing Persons, a North Carolina-based organization that assists with missing persons cases nationwide. Lisa is based in New Jersey and has become an advocate herself, helping others who have gone through the same thing her family has. One case she has worked on is the disappearance of Danielle Lopez, whose story we tell in Season 4.
