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. With extensive access to the original police tapes and interviews with the cold case detectives who worked to solve the crime, Blood and Water tells the story of a decades-long wait for justice for Leslie’s daughter and the cutting-edge investigative techniques that finally caught the killer. A six-part series from 20/20 and ABC Audio. New episodes Tuesdays.
