A documentary about an inmate on Florida's death row says the convicted killer might have been involved in the murder of O.J. Simpson's wife and her friend.
The Investigation Discovery show, "My Brother the Serial Killer," will be broadcast Wednesday.
The film is a look at Glen Rogers, who was convicted by a Florida jury in 1997 for killing a woman.
Rogers was also convicted of murder in California and is a suspect in homicides in several other states.
Rogers met Nicole Brown Simpson in 1994 when he was living in Southern California, his family says in the documentary.
A criminal profiler in the film says he received paintings by Rogers with clues possibly linking him to the murders of Simpson and her friend.
