/*Josef Fritzl*/, 73, also was charged with rape, incest, false imprisonment and slavery, said the state attorney's office in St. Poelten, west of Vienna.
"Despite recognizing the baby's life-threatening situation, he deliberately decided not to intervene" and get the ailing infant to a doctor, prosecutors said in their 27-page indictment.
Investigators say Fritzl has confessed to imprisoning and repeatedly raping his daughter Elisabeth - now age 42 - in a warren of windowless cellar rooms he built beneath his home starting in 1984, shortly after she turned 18.
Police say Fritzl told them he tossed the body of the infant who died into a furnace in 1996. They say DNA tests have confirmed he is the biological father of the six surviving children.
The retired electrician is expected to go on trial early in 2009.
If convicted of the murder charge, Fritzl would face life imprisonment. Austria, like other European countries, has no death penalty.
Prosecutors have said a psychiatric evaluation showed that Fritzl is mentally competent to stand trial. They reiterated that stance Thursday but recommended that Fritzl be moved to a special facility for mentally disturbed offenders so he can get counseling.
Under Austrian law, Fritzl has 14 days to appeal the charges. His lawyer, Rudolf Meyer, declined to say whether Fritzl would challenge the indictment and refused further comment.
Prosecutors also said it will be the first time that an Austrian is tried on a slavery charge.
Fritzl imprisoned his daughter and the children beneath his apartment building in Amstetten, 120 miles (75 kilometers) west of Vienna.
Authorities say Fritzl brought three of the surviving six children upstairs to live otherwise normal lives, and claimed to neighbors that his daughter - who he said had run away to join a religious cult - had left them on the family's doorstep.
The three other children remained imprisoned along with their mother until last April, when one of the youths - a teenage girl - became ill and was taken to a hospital.
Officials said it was the first time the three imprisoned children had ever been outside.
Fritzl, the indictment alleges, subjected his daughter to "multiple attacks" and terrorized her with threats that the cramped underground cell was rigged with booby traps to foil any attempt to escape.
Fritzl also threatened to release poisonous gas into the homemade prison, the indictment said.
It said the daughter was completely dependent upon Fritzl for her survival and had no choice but to provide "sexual services," the indictment added.
Police say they have no evidence to suggest that his wife was complicit.
His daughter, the children and Fritzl's wife have been getting counseling at an undisclosed location.
The case drew international attention to Austria, in part because it was reminiscent of another high-profile imprisonment case.
Natascha Kampusch was kidnapped as a 10-year-old while walking to school in Vienna. She was held in a windowless cell for 8½ years but staged a dramatic escape in August 2006 while her captor, Wolfgang Priklopil, was distracted by a phone call.
Kampusch, now 20, is a TV talk show host.
