ABC has released a trailer for Truth and Lies: The Menendez Brothers – American Sons, American Murderers documentary ahead of the January 5 premiere.

The two-hour docu special looks at the 1989 murders of a wealthy Hollywood executive and his wife in their Beverly Hills home.

They were convicted and sentenced to life in prison without parole in 1994.

The special uncovers the hidden clues of the Menendez family’s descent into hell including never-before-seen home movies and photos from the family vault and the testimony from members of the Menendez inner circle. The brothers’ best friends and neighbors, the lead detectives, lawyers and jurors on the case, and the family members profile the intimate details of the Menendez family, including Erik’s secret life.

The special is produced by ABC News. David Sloan is senior executive producer. Truth and Lies: The Menendez Brothers – American Sons, American Murderers airs Thursday, January 5 at 9 PM.
