The Investigation Discovery docuseries Is O.J. Innocent? The Missing Evidence concluded its run Tuesday night with the theory of O.J. Simpson's son, Jason Simpson, being the sole perpetrator in the infamous double homicide being debunked by law enforcement experts. 

Narrated by Martin Sheen, the final episodes, "The Charlie Theory" and "What Really Happened," included interviews with Kato Kaelin and O.J. Simpson's limo driver from the night of the slayings of Nicole Brown and Ronald Goldman. 

LAPD forensic psychologist Kris Mohandie and Rhode Island police Sgt. Derrick Levasseur worked with Dallas-based private investigator and author of O.J. Is Innocent and I Can Prove It, William Dear, concerning his theory about Jason Simpson's involvement in the murders. 

At the end of the sixth episode, Mohandie and Levasseur concluded O.J. Simpson murdered Brown and Goldman, but there may have been someone with him at some point that evening. Still, neither man believed that second person was Jason Simpson, according to the experts. 

The final two episodes began with "The Charlie Theory," in which the three discussed the book If I Did It: Confessions of the Killer, which was purportedly done by O.J. Simpson with ghostwriter Pablo Fenjves, who is interviewed in the episode. Fenjves discussed how the book addresses a hypothetical situation where O.J. Simpson committed the murders and someone was with him at the time. 

Kaelin, O.J. Simpson's house guest at the time of the murders, told investigators he was surprised Jason Simpson was not interviewed by police, which he assumed had occurred. Investigators said it had not because he was never a suspect. 

Dear also brought in another private investigator, Michael Martin, who claimed he was working a separate case in the area of Brown's home the night she was murdered and that he allegedly saw O.J. and Jason Simpson at the property.  

In "What Really Happened," Martin took a polygraph concerning his story. He passed. 

"However, just because Michael Martin is telling the truth about what he thinks he saw that night, that doesn't mean that's what actually happened," interjected Mohandie

Retired LAPD detective Tom Lange, who worked the original case and was the officer on the phone with O.J. during the infamous Bronco chase, said he didn't give much weight to Martin's tale. 

"Where was this guy 22 years ago? It's as simple as that," retorted Lange. He added that the LAPD would have looked into the account had they known about it. 

Neither Fred Goldman, Ron's father, nor Tanya Brown, Nicole's sister, said they bought the Jason Simpson theory, and both believed O.J. Simpson acted alone. 

"No chance," said Tanya Brown. "Nothing actually breaks my heart more than knowing people think that, especially when it comes to Jason. That really breaks my heart because he loved Nicole and she loved him." 

Fred Goldman said he always has based his opinion on the evidence. 

"I believe [O.J. Simpson] did it, and he did it alone," said Fred Goldman. "He did it with malice and no afterthought." 

The last episode ended with Dear saying he believed enough new evidence had been acquired concerning a second suspect to prompt a grand jury hearing, "and I will seek it."
