A man goes on trial in Austria today accused of locking his daughter in a basement for years. Josef Fritzl is charged with rape, incest, enslavement, as well as with murdering one of seven babies he fathered with his daughter. Bethany Bell reports from St Poelten. Prosecutors argued that the baby, a twin, might have survived if had been taken to a doctor. If he's on guilty of murder, Josef Fritzl could spend the rest of his life in jail. The charges of enslavement and rape carry sentences of 20 and 15 years. Josef Fritzl's lawyer Rudolf Mayer has told Austrian media that his client will plead guilty to most of the charges, but will contest the murder charge. He's also described the slavery charge as questionable. The trial is expected to last a week.
