It was the trial that defined a generation. This January, Investigation Discovery (ID) in association with Objective Media Group challenges everything you think you know about the trial of O.J. Simpson in a riveting new six-part docu-series IS O.J. INNOCENT? THE MISSING EVIDENCE. Narrated by Emmy Award-winning actor and activist Martin Sheen, and featuring exclusive new interviews with the families of Nicole Brown Simpson and Ron Goldman, the series follows investigators as they re-open the case that captivated the world, exposing the facts that were overlooked by authorities and questioning and dissecting each pivotal move in the original investigation.

From the infamous Bronco chase to updated forensics and DNA data to the examination of a potential murder weapon, each hour-long episode explores new possibilities and theories about what might have really happened on that fateful summer evening more than 20 years ago. IS O.J. INNOCENT? THE MISSING EVIDENCE, the world premiere three night event, kicks off on ID on Sunday, January 15 with back-to-back premieres starting at 9/8c. Following the U.S. premiere, IS O.J. INNOCENT? THE MISSING EVIDENCE will roll out in more than 130 countries and territories on Investigation Discovery and other Discovery networks, beginning in Denmark and Sweden on Sunday, January 22.

IS O.J. INNOCENT? THE MISSING EVIDENCE follows LAPD forensic psychologist Dr. Kris Mohandie and Rhode Island police sergeant Derrick Levasseur as they join forces with Dallas-based private investigator William C. Dear, who has devoted 21 years of his life to gathering critical new evidence about who may be behind this crime. They scrutinize the O.J. Simpson case from beginning to end, revealing compelling new information and investigating new theories in the murders of Simpson and Goldman.

The team re-examines several integral pieces of content from the original investigation, including canvassing the infamous Bronco and recreating the blood spatter from the murder scene. IS O.J. INNOCENT? THE MISSING EVIDENCE features interviews with Dr. Henry Lee, a forensic scientist who reviewed evidence at the crime scene, as well as other key players who have devoted their lives to seeing that justice be served, including Kato Kaelin, a key witness in the trial. The series also features a never-before-seen interview with a potential eyewitness to the crime. After taking viewers through the new theories, the team sits down for an intimate conversation with the victims’ families, including exclusive interviews with Fred Goldman and Tanya Brown, to hear their take on where things stand today.

Audiences are invited to continue the conversation with after show O.J. After The Evidence available to stream via IDGO, OnDemand, and on ID’s Facebook.
