June 7, 2010 -- The families of Natalee Holloway and Stephany Flores Ramirez are dissecting new video tapes released by authorities in Peru showing both Flores' last moments seen alive and the interrogation of Joran van der Sloot, the Dutch playboy suspected in Flores' murder and Holloway's disappearance.
"It just brings back the memories we have dealt with for the last five years," Holloway's aunt Linda Allison told "Good Morning America" today. "It is some comfort knowing know he has been arrested."
Van der Sloot was extradited back to Peru and charged with Flores' murder after fleeing the country for Chile last week just before her battered body was found in his hotel room. Police in Lima believe she was killed exactly five years to the day since Holloway, an American teenager, disappeared while on a school vacation to Aruba.
He has denied killing Flores, whose body was found with a broken neck, according to Peru authorities.
Van der Sloot was arrested twice in Holloway's disappearance, but was released both times without being charged. Holloway was never found.
"He does have an arrogance about him," Allison said. "He does seem to be above the law."
In the video of his interrogation, van der Sloot can be seen calmly explaining where he's been and what he's carrying, including a laptop, cash from different countries and photos. He even seemed friendly with the officers on his long drive back from Chile to Lima.
When investigators asked him where his credit cards were, van der Sloot answered in broken Spanish.
"I have those back in my hotel in Santiago," he said on the video. "I went up to my hotel room and I saw these things on the Internet and I had to leave quickly."
The calm demeanor van der Sloot showed on the video was a stark contrast to the stunned, even frightened look on his face as he was paraded in front of a media frenzy upon his return to Lima.
Allison, too, saw something different about van der Sloot as he was led by authorities, wearing a bullet-proof vest, "maybe one more a little intimidated or maybe afraid, when he was brought in with the police vest on for his protection."
"I think maybe he realizes the seriousness of it this time," she said.
Authorities also released surveillance video taken last week at the hotel in Lima. It shows van der Sloot getting his room key from the front desk. Police said they believe Flores was walking behind him, her back to the camera.
Moments later another camera upstairs captured the two walking into van der Sloot's room. It would be the last time Flores is seen alive.
Flores' father, Ricardo Flores, a well-known politician and race car driver, has said that what he saw on the video was not his daughter's normal walk.
Former FBI special agent Brad Garrett told "Good Morning America" that it seems Flores' is conflicted as she follows van der Slot both in the lobby and into his room.
"It's clear she's sort of stooped over and looking down," he said.
Van der Sloot was captured on camera leaving the hotel alone four hours later, wearing a different shirt and carrying a bag and a backpack.
Flores' body was discovered three days later. Though the hotel management declined to comment on what took so long to discover Flores, sources told ABC News that van der Sloot had pre-paid for a two-week stay and demanded that no one enter his room.
Garrett said that from van der Sloot's demeanor on the interrogation tapes, he appears to be trying to smooth talk investigators.
"He thinks he can talk his way out of just about anything," he said.
Ricardo Flores, who told ABC News that he considered his only daughter to be his "co-pilot" in life, said he has struggled to make any sense of her death.
" The spirit and soul of my daughter is with still us," he said. "I have four sons in body and a daughter in soul and spirit."
Van der Sloot Investigated in U.S. for Extortion Plot
As van der Sloot faces murder charges in Peru, he's also being investigated in the United States.
U.S. authorities told ABCNews.com that they launched an extortion investigation of van der Sloot six weeks ago, but they did not issue a warrant for his arrest until this week because they lacked sufficient evidence.
The federal extortion investigation began in late April, a spokeswoman for the U.S. Attorney's office in Birmingham said.
On May 10, $15,000 was wired to a Netherlands bank by someone in Mountain Brook, Ala., allegedly in exchange for a promise by van der Sloot to provide information about what happened to Holloway and the whereabouts of her remains.
Van der Sloot had for five years been the prime suspect in the disappearance on Holloway, a high school student from Mountain Brook who vanished in Aruba on May 30, 2005.
Van der Sloot, a Dutch national who lives in Aruba, was arrested Thursday in Chile and was extradited today to Peru to face murder charges in Flores' death. He told authorities he met Flores, but denied killing her.
For several weeks van der Sloot had been on the radar of American officials who, in a criminal complaint released Thursday, said he planned to extort $250,000 from the unidentified victim.
A criminal complaint alleging the extortion was filed Thursday, just days after Flores was found dead and van der Sloot had fled to Chile.
Authorities said their charges were not the result of the Peru death.
"This was completely separate and before the girl was killed in Peru," said Peggy Sanford, spokeswoman for the U.S. Attorney's Office in Birmingham. "This investigation had been going on. It was a complete coincidence and tragedy that the other woman was murdered."
The complaint does not name the person whom van der Sloot was trying to extort, by providing information about Holloway's death, but Sanford suggested, van der Sloot had initiated contact by approaching the alleged victim.
"He extorted, or attempted to extort someone, an individual, in exchange for the location of Natalee Holloway's remains and information about her death. Mr. van der Sloot made efforts to extort someone and get money," said Sanford.
U.S. law enforcement, however, may never get to try van der Sloot for the alleged extortion scam. He arrived in Peru today under armed guard.
Famed criminal defense lawyer Roy Black told ABC's "Good Morning America" that, "The murder case in Peru takes precedence over" the extortion charges, and that the chances of van der Sloot getting extradited to Alabama "are zero."
"He's going to get a very long sentence in Peru," Black said. "By the time he gets out of jail, if he ever does, this would be a footnote in history."
The lawyer said, however, that the Holloway disappearance could be used "as evidence of proof in Peru," and the Holloway family may ask a Peru court "for a longer sentence because of Natalee's murder."
