Natalee Holloway vanished in May 2005, and her disappearance has remained a mystery for law enforcement and her family. Her mother told NBC's "Today" that she still wants a resolution for her daughter.

“You’re never over feeling the loss of your loved one,” Beth Holloway said.

Joran van der Sloot, the Dutch man Natalee Holloway was last seen with, is serving a 28-year sentence for killing a Peruvian student on the fifth anniversary of Holloway’s disappearance. He’s currently jailed in Peru.

Beth Holloway said she takes “great comfort” in knowing Van der Sloot is in prison, but it’s not enough for her.

“Justice is being served for Stephany Flores, thank God,” Beth Holloway said. “And he is in prison in Peru. But justice has not been served for Natalee ... That would be justice to me, to see him serve prison time in the United States. That would be justice for Natalee.”

Van der Sloot faces charges in the U.S. for accusations that he tried to extort money from the Holloway family in exchange for false information about where Natalee’s remains could be found.
