Holloway Dad: Van der Sloot Should Tell All

Now that police in Peru say Dutchman Joran van der Sloot has confessed to killing a young woman in his hotel room, the father of Natalee Holloway says he should tell everything he knows about the Alabama teen who went missing in Aruba in 2005.

In an interview Tuesday on ABC's "Good Morning America" Dave Holloway of Meridian, Miss., said, "He confessed to this one ... I would like for him to tell everyone what happened." He added, "Hopefully this is his last victim."

Police in Lima said late Monday that Van der Sloot admitted killing 21-year-old Stephany Flores.

He has been the main suspect in the disappearance of Holloway five years ago on a class trip to Aruba, and is charged with trying to extort $250,000 from her family in exchange for information about the case.

Separately Tuesday, Natalee Holloway's mother said that it's been a stressful time for her but she hopes a new resource center named for her daughter will help guide families of missing persons.

Beth Holloway spoke briefly to launch the Natalee Holloway Resource Center at the National Museum of Crime & Punishment in Washington.

Beth Holloway said people should keep the Flores family in their hearts and prayers.

A museum official said Holloway could not comment on her daughter's case or recent developments because of an FBI directive.
