Barbara Walters Presents: American Scandals

In one of the most famous murder stories of all time, Nicole Simpson and Ron Goldman were stabbed to death. The evidence pointed to Nicoles ex-husband O.J. Simpson but the jury found him not guilty. 20 years later, Barbara talks with Kato Kaelin again.

Why did Erik and Lyle Menendez murder their parents? Barbara shares exclusive details about the case, along with never before seen letters from Erik. And she uncovers a bombshell: a childhood message that could possibly grant the brothers a new trial.
