someone later hid her body. Dompig also stated that Aruba had spent about $3 million on the investigation, which was about 40% of the police operational budget. Dompig indicated that there was evidence that pointed to possession (though not necessarily use) of illicit drugs by Holloway. Members of Holloway's family have denied that she used drugs. On April 11, 2006, Dave Holloway published a book—co-authored with R. Stephanie Good and Larry Garrison—called Aruba: The Tragic Untold Story of Natalee Holloway and Corruption in Paradise, that recounted the search for his daughter. 2006 arrests of new suspects; Dutch investigation takeover On April 15, 2006, Geoffrey van Cromvoirt was arrested by Aruban authorities on suspicion of criminal offenses related to dealing in narcotics which, according to the prosecutor, might have been related to the disappearance of Holloway.
