Could incest suspect Josef Fritzl have been involved in an unsolved murder 22 years ago?
Austrian police say they have no evidence, but they've widened their investigation into the murder of a young woman, Martina Posch, whose body was found on the shore of a lake in November 1986.
Fritzl's wife owned part of an inn and camping ground on the other side of the lake, and police say it's possible that he could have been in the area.
Fritzl, 73, is accused of imprisoning his daughter for 24 years, raping her, and fathering seven children with her.
