As Ryan Murphy’s “American Crime Story: The People v O.J. Simpson” series and Ezra Edelman’s epic documentary “O.J.: Made in America” both continue to collect trophies on the fall awards circuit, veteran actor Martin Sheen is set to premiere his own true-crime series on the trial of O.J. Simpson, which he previously said would unfold in a similar manner as Netflix’s hit docu-series “Making a Murderer,” focusing on alleged evidence that he claims exonerates Simpson in the 1994 murders of Nicole Brown Simpson and Ronald Goldman.

Sheen’s series has now officially found a home as Investigation Discovery has picked up what will be a 6-part docu-series about the O.J. Simpson trial, which will be titled “Is O.J. Innocent? The Missing Evidence.”

Sheen teamed up with Dallas-based investigator William Dear, who says he has spent 21 years collecting what he calls “hard evidence” that he believes exonerates Simpson of the double murders.

“People are fascinated with true crime. I know the time is right for people to look at this O.J. thing,” Dear said in a statement earlier this year, adding that the project, like Netflix’s “Making a Murderer,” will “raise doubts” about Simpson’s perceived guilt (although, unlike Steven Avery in “Making a Murderer,” Simpson was acquitted of the murders in 1995, avoiding prison time, and would later be found liable in a civil suit in which he was ordered to pay $33.5 million to the victims’ families).

And about the series, he shared the following: “It’s not going to be talking heads. These are going to be facts, not hearsay, not soft evidence but hard evidence… We have diaries. We have pictures of [another suspect that they believe was overlooked] wearing a cap that was found at the crime scene. We have the vehicle the suspect was driving. We have a witness. We feel very confident in what we’ve been able to put together.”

William Dear is also the author of the 2012 book “OJ is Innocent and I Can Prove It.”

“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 Dear, to scrutinize the O.J. Simpson case from beginning to end, revealing 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. The 6-part series 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. And 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.

“The prosecution of O.J. Simpson is interwoven into the fundamental cultural fabric that defines the 20th century, representing a watershed moment in our nation’s system of justice. Therefore, it may be hard for many of us to accept new theories that challenge common beliefs and perceptions held in this country,” said Henry Schleiff, Group President, Investigation Discovery, American Heroes Channel and Destination America. “Indeed, it is imperative to remember, however, that no one has ever been convicted of the murders of Nicole Brown Simpson and Ron Goldman in a court of criminal law – and, accordingly, with unprecedented access and evidence never before investigated, we offer, today, a new take on the case everyone thought they knew.”

Investigation Discovery has set the world premiere three night event for “Is O.J. Innocent? The Missing Evidence,” for Sunday, January 15 with back-to-back premieres starting at 9/8c.
