A US documentary claims a Florida death-row inmate might have been involved in the murder of OJ Simpson's ex-wife and her friend.
But the claim on the Investigation Discovery show My Brother The Serial Killer has been criticised by one victim's family and was viewed with scepticism by a detective and a prosecutor who dealt with the convict.
The film focuses on Glen Rogers, a carnival worker whom Florida jurors convicted in 1997 of killing a woman in a Tampa motel room. Rogers, now 50, was also convicted of murder in California and is a suspect in killings in Mississippi, Louisiana and Kentucky and possibly several other states.
Most of his victims were women he had met in bars while drifting across the country and all were stabbed to death.
Rogers was arrested in November 1995 near Waco, Kentucky, after a nationwide manhunt for the so-called Cross-Country Killer and a 100mph chase.
Anthony Meoli, a criminal profiler, says in the film that he received a painting by Rogers of the murder weapon used in the 1994 murders of Ms Simpson and her friend Ronald Goldman. "I believe that Glen believes he killed them," said Mr Meoli, of Atlanta, who has received more than 1,000 letters from Rogers and has interviewed him in prison.
Ex-football star and actor Simpson was accused of the killings but the so-called "trial of the century" in Los Angeles ended with his acquittal in 1995.
Simpson never gave evidence at the criminal trial, but memorably demonstrated in court that a glove found near the scene did not fit his hand. He spoke at length in a wrongful-death trial that led a Los Angeles civil court jury in 1997 to find him liable for damages in the case.
Simpson is currently serving a prison sentence in Nevada after being convicted in 2008 of leading five men, including two with guns, in a September 2007 confrontation with two sports memorabilia dealers and a middleman at a Las Vegas casino-hotel.
