After hearing testimony from his daughter, Josef Fritzl has finally pleaded guilty to all counts, admitting to what even he calls "my sick behavior," which included keeping his then-18-year-old daughter Elisabeth captive in a windowless cell under the family's home and raping her repeatedly.

His charges include enslavement, rape, incest, coercion and negligent homicide. The latter charge is the result of an incident in April 1996, when one of Fritzl's babies died after he failed to take it out of the cellar for medical treatment. "I don't know why I didn't help," he said. "I just overlooked it. I thought the little one would survive."

He faces up to life imprisonment, which a psychiatrist recommends he spend in a mental ward. Life behind bars hardly seems like punishment enough for what he did to his daughter, but it's a start.
