Keith Morrison and Dateline producer Tim Uehlinger join Andrea Canning to discuss their episode, “Secrets Unmasked.” It’s the story of Regina Hicks, a young Ohio mother whose body was found in the passenger seat of her submerged car in 2001. Her manner of death was ruled undetermined, and for decades the case remained a mystery. Then an alleged arson scheme involving a custom-made face mask prompted investigators to take another look at Regina’s death. Keith and Tim discuss the twists and turns that ultimately led to justice, including the pivotal role of witness Steve Gates, who broke his silence after nearly 25 years. Keith also shares an extra clip from his interview with Steve, who explains why he is no longer afraid of Regina’s killer. Plus, we answer your questions from social media.
