The murder charge relates to an infant named Michael Fritzl who died soon after birth , allegedly from lack of medical care , State Prosecutor Gerhard Sedlacek says . A neo-natal expert gave evidence Tuesday in relation to the murder charge . As he had Monday when the trial opened , Fritzl concealed his face behind a file binder as he arrived in court to shield himself from reporters , television cameras and photographers and escorted by a phalanx of police officers . Later Tuesday he dropped his guard and was pictured with the binder by his side , talking to security guards . During the trial , prosecutors have painted a chilling picture of the more than two decades Elisabeth spent in the cellar of the family home in Amstetten with three of her children . Fritzl took three other children upstairs , authorities have said , telling his wife and other relatives that the missing Elisabeth had dropped them at the house . The woman and the remaining children never saw daylight , prosecutors said , and Fritzl went away for long periods of time , causing them to go hungry when he did not bring them food . Watch Fritzl 's first day in court » . To punish them , prosecutors said , Fritzl sometimes turned the power off in the cellar for up to 10 days . In addition , they alleged , Elisabeth was often sexually assaulted in front of the children . The case first came to light in April 2008 when Elisabeth 's then-19-year-old daughter , Kerstin , became seriously ill with convulsions , and Elisabeth persuaded her father to allow the girl to be taken to a hospital . Hospital staff became suspicious and alerted police , who discovered the family members in the cellar . Police said Fritzl confessed to them that he had sex with his daughter , kept her and their children in captivity , and burned the body of the infant in an oven in the house . Elisabeth told police the infant was one of twins , and died a few days after birth . When Elisabeth gained her freedom , she told police her father began sexually abusing her at age 11 . Seven years later , she said , he drugged , handcuffed and locked her in the cellar . To back up his story that she had run away , Fritzl forced Elisabeth to write letters , authorities have said . Defense attorney Rudolph Mayer has said his client , 73 , expects to spend the rest of his life in prison . Under Austrian law , if Fritzl is convicted on several offenses , he will be given the sentence linked to the worst crime . The charges he faces are : . • Murder : The infant who died in 1996 died from a lack of medical care , the state prosecutor said . The charge carries a sentence of life in prison . • Involvement in slave trade : From 1984 until 2008 , prosecutors allege , Fritzl held his daughter , Elisabeth , captive in a dungeon , abused her sexually and treated her as if she were his personal property -- in a situation similar to slavery . If he is convicted , the sentence could range from 10 to 20 years in prison . • Rape : Between August 30 , 1984 , and June 30 , 1989 , Fritzl `` regularly sexually abused Elisabeth , '' according to the prosecutor . The sentence could be from five to 15 years in prison . • Incest : Parallel to the rape charge . It carries a sentence of up to one year . • Withdrawal of liberty : Three of the children Fritzl had with Elisabeth were illegally held captive in a dungeon with no daylight or fresh air , according to prosecutors . That charge carries a sentence of one to 10 years . • Assault : Between August 28 , 1984 , and April 26 , 2006 , Fritzl repeatedly threatened Elisabeth and their three children with gas and booby traps as warnings in case they tried to escape , authorities allege . The sentence would range from six months to five years . CNN 's Diana Magnay and Frederik Pleitgen in St. Poelten and Melissa Gray in London contributed to this report .
