Today, we're sharing an early look at our next podcast series from 20/20 and ABC Audio, "Blood and Water." In 2001, Leslie Preer was found brutally murdered, her body left in the shower of her home in the wealthy suburbs of Washington, D.C. Investigators initially set their sights on Leslie’s husband as the prime suspect — until bombshell DNA evidence revealed the presence of an "unknown male" at the scene. Episodes will air in the 20/20 podcast feed weekly on Wednesdays beginning April 29. Or to get new episodes early, follow "Blood and Water" for free on Apple Podcasts, Spotify, Amazon Music, or wherever you listen to podcasts. Learn more about your ad choices.
