Natalee Holloway family attorney sees "opportunity for the truth" as Joran van der Sloot to appear in court

Joran van der Sloot, the last person known to see Natalee Holloway alive, is set to face a judge in Birmingham, Alabama, on Friday. Van der Sloot was extradited Thursday from a prison in Peru, where he is serving a 28-year sentence for murdering a woman in 2010.

Van der Sloot is not charged with killing Holloway, who was declared dead several years ago. The charges he faces in Birmingham instead revolve around his alleged attempt to extort money from her family. 

In 2010, a federal grand jury indicted the Dutch national on charges of attempting to extort $250,000 from Holloway's family in exchange for information about the location of her body, which turned out to be false.
