Van der Sloot was charged in Holloway's home state of Alabama in an alleged extortion scheme.

"He extorted, or attempted to extort someone, an individual, in exchange for the location of Natalee Holloway's remains and information about her death," said Peggy Sanford, spokeswoman for the U.S. Attorney's office in Birmingham.

Just one day after Holloway was declared dead, Van der Sloot was sentenced to 28 years in prison for killing Stephany Flores in Peru. Van der Sloot's lawyer said he had killed Flores because of the psychological trauma of being accused in the Holloway case.

"Yes, I want to plead guilty. I wanted from the first moment to confess sincerely," Van der Sloot said in court. "I truly am sorry for this act. I feel very bad."

May 2015:

A new witness comes forward who says he saw what happened to Holloway. Holloway's father also speaks out, saying he believes the witness.
