'Is O.J. Innocent? The Missing Evidence'

Experts in the new Investigation Discovery docuseries Is O.J. Innocent? The Missing Evidence continued to examine a theory in Monday's third and fourth installments that O.J. Simpson's son Jason may have killed Nicole Brown and Ron Goldman.

The six-part true-crime series premiered Sunday and wasted no time introducing an alternate version of June 12, 1994, to the one that gripped the nation following the double homicide.

Narrated by Martin Sheen, the latest episodes, "Person of Interest" and "About the Alibi," revolve around LAPD forensic psychologist Kris Mohandie, Rhode Island police Sgt. Derrick Levasseur and Dallas-based private investigator William Dear examining Dear's Jason theory.

In the third episode, among the clues Dear (author of O.J. Is Innocent and I Can Prove It) said he had obtained are journals he claims belonged to Jason.

The investigators consulted with a handwriting expert and a forensic psychologist in an effort to try and confirm who filled out the notebooks and what that person might be capable of doing if they had the rage that's suggested in the writing. The law-enforcement experts also went over a taped deposition that Jason gave when his father was sued by the Goldman family following his acquittal.

Among the people interviewed in "Person of Interest" is retired LAPD officer and former Simpson family friend Ron Shipp, who testified against O.J. during his criminal trial.

Shipp was adamant O.J. was the perpetrator behind the double homicide and tells the series' investigators there was no need for the police to look into Jason as a suspect.

"How much evidence of Jason do you see at the scene? How much evidence of Jason do you see at the Bronco? How much evidence of Jason do you see at Rockingham [O.J.'s home]? Zero," said Shipp.

The investigators also interviewed a former employer of Jason's and a criminal-defense investigator who worked with the "Dream Team" in an attempt to better understand the subject of Dear's theory.

In "About the Alibi," the investigators tried to reach Jason by phone, but are unsuccessful. They also looked into where Jason was the night of the murders and try to determine if Dear's theory is sound.

Included in the materials the investigators went over was Jason's alleged time card from the night Brown and Goldman were killed and more of Jason's taped deposition from his father's civil case.

In both episodes, the investigators talked with people who knew Jason in the past and discussed his supposed temper. However, neither person wanted to be shown on camera or identified.

Dear also revealed he hired another private investigator to obtain more information about Jason's life now, which struck a chord with Mohandie.

"Seeing this really humanized Jason for me," began Mohandie. "It may just be the psychologist in me talking, but it made it very real that what we're doing here is we're looking at a person who's in our world right now, just trying to get by. And yeah, he may be aloof and reclusive, but think about it: His dad is in prison [for an unrelated crime]. He lost a woman who he cared about. For me, it brought it home that we better be darn careful about where we're going with this because this is a person who is just trying to live life."

The Investigation Discovery docuseries concludes Tuesday with "The Charlie Theory" and "What Really Happened."
