Francis Lee Bailey Jr., better known to the general public as F. Lee Bailey, was an American criminal defense attorney. Bailey's name first came to nationwide attention for his involvement in the second murder trial of Sam Sheppard, a surgeon accused of murdering his wife. He later served as the attorney in a number of other high-profile cases, such as Albert DeSalvo, a suspect in the "Boston Strangler" murders, heiress Patty Hearst's trial for bank robberies committed during her involvement with the Symbionese Liberation Army, and US Army Captain Ernest Medina for the My Lai Massacre. He was a member of the "Dream Team" in the trial of former football player O. J. Simpson, who was accused of murdering Nicole Brown Simpson and Ron Goldman. He is considered one of the greatest lawyers of the 20th century.

Samuel Holmes Sheppard was an American Osteopath. He was convicted of the 1954 murder of his pregnant wife, Marilyn Reese Sheppard, but the conviction was eventually overturned by the U.S. Supreme Court, which cited a "carnival atmosphere" at the trial. Sheppard was acquitted at a retrial in 1966.
