A documentary about an inmate on Florida's death row says that the convicted killer may have been involved in the 1994 murder of OJ Simpson's ex-wife and her friend.
The film, shown on US television last night, alleges that carnival worker Glen Rogers, who was convicted in 1997 of killing a woman and who has also been convicted of another murder, met Nicole Brown Simpson in California in 1994.
But the claim on 'My Brother The Serial Killer', has been criticised by one victim's family and was viewed with scepticism by a detective and a prosecutor.
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 Ronald Goldman.
"I believe that Glen believes he killed them," said Mr Meoli, 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 he was acquitted in 1995.
