In June 2010, a federal grand jury based in Alabama indicted van der Sloot on charges of allegedly attempting to extort $250,000 from Holloway's mother, Beth.

Van der Sloot offered to provide what turned out to be bogus information about the whereabouts of Holloway's remains in exchange for the money, according to the indictment against him.

He was allegedly given $25,000, which authorities say he used to travel to Peru for a poker tournament.

In March, Peru agreed to extradite van der Sloot to the United States on these charges sometime after he's eligible for release, in 2038, for Flores murder.

Peruvian media have raised the possibility that van der Sloot got married to avoid extradition to the United States.

But Altez, his defense lawyer, this spring dismissed that suggestion, saying then that the wedding shouldn't be "a big deal."

"He's getting married because he's in love and is having a child," Altez said in May. "There are no hidden agendas."
