Suspect's Dad Nabbed?!

Just saw a news alert regarding the Halloway disappearance case, it seems that the father of Joran Van der Sloot was arrested today ! Wow, that came as a surprise, as this situation just gets stranger by the day. First, a girl leaves in a car with 3 men, she then disappears without a trace, police question the last 3 young men she was seen with, at which time they apparently lied to police and implicated two security guards, the guards are arrested while the 3 men remain free for a long number of days, police realize they were given bad info regarding the security guards and arrest the 3 men, the security guards are then released days later, the Halloway family meets with the Van der Sloot family and calls the father "a slimeball who knows something", the stories of the 3 men being held begin to unravel and contain contradictions, the American press and later the world press invade the island, Aruban travel officials claim tourism isn't effected by the case, but is actually "up in numbers" (guess they didn't factor in the number of reporters who had come to the island and booked accomodations), radio talk-show host in the U.S call for a boycott of Aruba for potential tourists, Aruban officials become angered by "an orchestrated attempt to apply pressure on the investigation", the father of one of the men is brought in for questioning, the father is later captured running from reporters in chase, a Texas search organization volunteers to help with the search on a private level, the same search organization is publicly welcomed by Aruban officials but is quietly tied up in red-tape regarding the bringing of search dogs to the island, the father is ultimately arrested on undisclosed suspicions. Whew ! and that is where the situation is at the present moment (see what I mean about the whole thing being a bit strange?), 24 days since the initial disappearance, and no closer to resolution. What is your best guess as to what happened? My prayers still go out for Natalee Halloway, and her family.
