TAMPA, Fla. (AP) — A documentary says a Florida death-row inmate might have been involved in the murder of O.J. Simpson’s ex-wife and her friend, a claim being criticized by one victim’s family and being looked at skeptically by a detective and a prosecutor who dealt with the convict.

The Investigation Discovery show, “My Brother the Serial Killer,” will air Wednesday. The film is a look at Glen Rogers, a carnival worker whom Florida jurors convicted in 1997 of killing a woman in a Tampa motel room.
