(CNN) – Joran van der Sloot, who was convicted of killing one woman and linked to the high-profile disappearance of another, is back in the news.
In 2012, van der Sloot was convicted of robbing and killing Stephany Flores.
He has also been linked to the disappearance of American teenager Natalee Holloway, who vanished in Aruba in 2005.
Earlier this year, he married Leidy Figueroa inside the Peruvian prison where he’s an inmate.
Figueroa says her husband was “seriously injured” in a stabbing at the prison, but a top prison official is calling her account an outright lie.
She told reports that he was stabbed once in the shoulder and once in the waist.
She claimed that after visiting him on Sunday, she was able to smuggle his bloody shirt out of the facility.
Jose Perez Guadalupe, director of Peru’s National Penitentiary Institute, told a television station that Figueroa’s assertions were untrue and claimed she is a “compulsive liar.”
“For starters, no woman in her right mind goes to a maximum-security prison and marries the biggest killer there,” Guadalupe said.
Van der Sloot is serving a 28-year sentence for the murder.
When he is eligible for release, he is expected to be extradited to the United States to face charges in the Holloway case.
The Alabama 18-year-old was last seen leaving an Aruba nightclub in 2005 with van der Sloot and two other men.
Van der Sloot was indicted on federal charges of extortion and wire fraud after American authorities accused him of extorting money from Holloway’s mother by offering bogus information about her daughter’s disappearance.
