Josef Fritzl, an Austrian man who held his daughter captive in his basement as a sex slave for 24 years, fathering seven of her children, may be removed from a psychiatric detention center to a regular prison, according to global reports.
Fritzl, 87, will remain in the psychiatric prison while prosecutors evaluate the situation, The Associated Press reported.
Fritzl was sentenced to life in prison a year later for incest, rape, coercion, false imprisonment, enslavement and negligent homicide after he killed one of the sons he fathered soon after the baby was born, according to AP and Reuters.
Investigators said in 2009 that the incestuous killer burned his son's body in a furnace.
A panel of Austrian judges made the decision Wednesday, and prosecutors appealed, court spokesman Ferdinand Schuster told the Austria Press Agency.
Fritzl's daughter, Elisabeth disappeared in 1984 when she was 18 years old. She was found in 2008 after 24 years of captivity and brutal abuse. Authorities charged Fritzl that same year.
Prosecutors said at the time that Fritzl lured her into his windowless basement, drugged her and locked her in a room while telling those who asked about her whereabouts that she had run away.
"He forced Elisabeth into slave-like conditions ... shut her away in the cellar and made her totally dependent on him, forcing her into sexual acts and treating her as if she was his own property," the St. Poelten provincial prosecutors’ office said in a 2009 statement, according to Reuters.
Prosecutors also alleged that Frizl threatened to kill Elisabeth and gas their children to death
