Prosecutors have accused Fritzl of murder for letting a baby named Michael die shortly after birth in the cellar. Fritzl had maintained the baby was still-born and said he burnt the body in a boiler.
But he admitted on Wednesday that he was present at Michael's birth and that he had developed breathing problems.
'I don't know why I didn't help,' he told the court. 'I should have noticed that the baby was not doing well. I just hoped it would survive.' A psychiatrist told the court that Fritzl felt he was 'born to rape,' and said he should be placed in a psychiatric facility because there was a risk he would commit new offences.
'The danger is still very much there that he will reoffend if he is not treated,' said Adelheid Kastner.
'It is necessary that he continue being treated until he can no longer be classified as dangerous.' When Dr Kastner quizzed Fritzl as to why he had chosen Elisabeth, the third-eldest of his seven legitimate children, as his victim, 'his reply was that she was most like me. She was as stubborn as me, as strong as me. The stronger your opponent, the bigger the victory,' she quoted him as saying.
Three children were brought up to live with Fritzl and his wife Rosemarie while three lived with Elisabeth and never left the dungeon until their release last April.
The trial was adjourned so the three judges could compile a catalogue of questions to help the jury decide whether Fritzl was guilty as charged.
The questions would be read to the jury Thursday, after which defence and prosecution would make their closing statements.
The jury would then retire to reach its verdict, which need not be unanimous, but requires a simply majority.
Once the verdict has been reached, the jury and judges would together consider what sentence to hand down.
They could decide to send Fritzl to a mental facility, court spokesman Cutka told journalists.
Experts and judges would then review Fritzl's case on a yearly basis.
'If the expertise concludes there has been an improvement and he can be released from such a facility, he will then serve any remainder of his sentence (in a prison),' Cutka said. -- AFP
