Former football great and occasional actor O.J. Simpson was acquitted of killing his ex-wife and her friend. No one else has been tried for the double slaying. Simpson is now in prison for an unrelated armed robbery.
The New York Post said the ID documentary "My Brother the Serial Killer" focuses on Florida death row inmate Rogers, who is suspected of killing as many as 80 people, including, the documentary says, Simpson and Goldman.
The film said Rogers admitted to a criminal profiler and family members he killed Simpson and Goldman nearly 20 years ago. In addition to his confessions, receipts show Rogers had been working construction near the scene of the crime shortly before the two were stabbed to death, the Post said.
Rogers, who also seemed aware of details about the killings no one else knew, said O.J. Simpson paid him to break into his ex-wife's house and steal a pair of $20,000 earrings, the newspaper reported.
Rogers also alleges Simpson told him to kill "the bitch" if necessary, the newspaper said.
The film is to air Wednesday.
The Post did not say if authorities are officially investigating Rogers as a suspect in the deaths of Simpson and Goldman.
Goldman's father, Fred, told TMZ he still believes O.J. Simpson killed his son and Nicole Simpson.
"O.J. Simpson murdered Nicole Brown Simpson and Ron Goldman. The criminal trial showed overwhelming and monumental evidence that O.J. Simpson was the killer. There was no contrary evidence other than guess, innuendo and rumor," Fred Goldman said in a statement to TMZ Monday.
"The fact of the acquittal at the hands of the jury will never wash away this murder from the hands of O.J. Simpson, no matter how many Glen Rogers pop up on the media radar screen."
