In 2016, Robert F. Kennedy. Jr. published “Framed: Why Michael Skakel Spent Over a Decade in Prison for a Murder He Didn’t Commit," which attempted to clear his cousin’s name.

Laura Coates re-explores the tragic 1975 murder of 15-year-old Martha Moxley.

Adolph Hasbrouck's attorney says the only reason his client was ever linked to Moxley's murder was a false statement, and the association has had a "horrible impact" on his life.

Dorothy Moxley says that, as a schoolteacher and 'not the smartest woman in the world,' journalists and investigators seeking the truth about Martha's murder have been her "angels."

Private Investigator Larry Holifield says Michael Skakel would have let the truth slip at some point if he was guilty of killing Moxley. Skakel also believes his brother, Tommy, had no part in it, but should police have looked closer at Tommy?

Private Investigator Larry Holifield tells Laura Coates that Ken Littleton was one of the "prime suspects" in Moxley's murder that he and Robert F. Kennedy Jr. looked into for their 2016 book.

Dorothy Moxley says she knows who killed her daughter, Martha, in 1975. Experts say evidence has been suppressed over the decades, and Laura Coates hopes an explosive new video might help bring Martha's killer to justice.

In 2002, Chuck Seigan testified that Michael Skakel told classmates he was intoxicated the night Martha Moxley was murdered, and that he did not know if he was the one who killed her.

In the late 1990s, Michael Skakel made an audio recording for his unpublished memoir, “Dead Man Talking: A Kennedy Cousin Comes Clean,” which included his account of the night Martha Moxley died.

Dr. Katherine Maloney, a pathologist, discusses the autopsy report of 15-year-old Martha Moxley, who was bludgeoned and stabbed to death with a golf club the night of October 30, 1975. Maloney believes that Moxley's assailant was possibly very angry or enraged to commit such a violent killing. To this day, it is still unclear what happened to Moxley.

In conversation with former federal prosecutor Laura Coates, John Moxley, the brother of slain 15-year-old Martha Moxley, reflects on the trial of his former neighbor, Michael Skakel, who was also 15 at the time of the slaying. Michael was found guilty of Martha's murder in 2002, but after a series of appeals, his conviction was overturned. To this day, Michael maintains his innocence.
