The Sheridans’ eldest son Mark is consumed with getting to the bottom of what happened to his parents. As the lawyer for Governor Chris Christie’s election campaign, Mark is in a unique position to uncover answers. Instead, he’s met with roadblock after roadblock. The questions really pile up when he learns that detectives haven’t even interviewed several key witnesses or completed a thorough investigation of the crime scene. Not only that, a key piece of evidence is missing.

New voices interviewed in episode:

• Barry Jansen, retired forensic technician for the Somerset County Prosecutor's Office

• Tom Draper, Sheridans’ neighbor

• Michael Baden, medical examiner hired by the Sheridan brothers

A previous version of this episode referred to Mark Sheridan as the “personal lawyer for Chris Christie.”  In fact, he was the personal lawyer for the Chris Christie campaign.  We have updated the episode to correct this.
