The parents of missing teenager Natalee Holloway have condemned her accused murderer after he "confessed" on tape.
In the video, Joran Van der Sloot admits to an associate, Patrick Van der Eem, that he was with Holloway when she collapsed on a beach and died in May 2005 while vacationing in Aruba. He goes on to say he and a friend disposed of the body. (The 20-year-old now claims he lied during the secret recording
, which was arranged by Dutch crime reporter Peter de Vries.)
"I do believe the words that Joran was admitting," her mother, Beth Twitty, told Larry King Live
Thursday night. "I can't imagine having just an utter disregard for someone's life."
Natalee's father, Dave Holloway, also described his disbelief when first watching the video.
"I just couldn't believe what I was seeing," he told Nancy Grace on CNN's Headline News
. "You just can't believe that a person would stoop this low and have no lack of respect or remorse. I mean, he – he has literally destroyed that island. And to top it all off, he laughs."
Holloway hopes the tape will force Van der Sloot to give a full description of that night. "I just hope he comes clean," he said. "He's got an account to settle, and I hope he settles it on this earth this time. If he doesn't, you know, God bless him."
In December, authorities in Aruba officially closed
the Holloway case, admitting there was not enough evidence to charge anyone with the 2005 disappearance
Most recently, a Los Angeles Superior Court judge ruled that a defamation lawsuit
against TV's Dr. Phil
– launched by Van der Sloot's accused co-conspirators, brothers Deepak and Satish Kalpoe – can proceed.
