ST. POELTEN, Austria (CNN) -- Josef Fritzl, the Austrian man accused of repeatedly raping his daughter in a cellar dungeon for decades, has admitted guilt on all charges, including responsibility for the death of one of seven children he fathered by his daughter.

Fritzl had already pleaded guilty to incest and other charges, but previously denied charges of murder and enslavement.

But on Wednesday Fritzl told the court in St. Poelten, 70 kilometers (40 miles) west of Vienna, he had changed his mind after watching his daughter Elisabeth's video testimony earlier in the week.

In a weak voice, the 73-year-old said he was in the cramped cellar when the baby, called Michael Fritzl, was born.

He noticed the child was breathing heavily, he said, but did not think the baby would die and opted not to seek medical attention.

Fritzl told the court he was therefore probably responsible for the child's death. He had previously told police he had burned the baby's body in a furnace.

"This is a major development in this trial," said CNN's Frederik Pleitgen. "The murder charge is really the centerpiece of this whole trial because only a murder conviction could get Josef Fritzl a life sentence." Watch what Fritzl's new plea means for the case »

Fritzl's new plea could speed proceedings although the jury must still decide on his guilt or innocence, a court spokesman said. "The admission of guilt alone is not enough," spokesman Franz Cutka told reporters.

Observers had said the murder charge might be difficult to prove because the only evidence was testimony from Elisabeth and a neo-natal expert. A verdict had been expected on Thursday.

Wednesday's proceedings will involve psychiatrists talking about Fritzl and his daughter, and a technical expert who will testify about the construction and living conditions of the cellar.
