(CNN) — Police have released a 19-year-old man who was arrested on suspicion of involvement in the disappearance of Natalee Holloway, Aruban prosecutors said Monday. "Today, the suspect G.v.C. has been released from police custody," said a statement from the prosecutor's office. "He has been released because the grounds for his detention are no longer there. He remains a suspect." The man, who was arrested on April 15, has not been charged with a crime, and no one has been charged in connection with Holloway's disappearance in May of 2005. A search of the tiny island by Dutch Marines, the FBI and hundreds of volunteers failed to find her.
The Aruban newspaper Diario identified "G.v.C." as Geoffrey van Cromvoirt, a brother of a police officer, and published photographs of him attending his sister's swearing-in ceremony. Monday's statement from prosecutors also said that another man had been arrested in the case over the weekend, and also was released. "On Saturday, April the 22nd, a 20-year-old man with the initials E.B. was arrested in the Holloway case. He was released after the interrogation period of 6 hours," the statement said. In another development, Aruban Police Commissioner Gerold Dompig told The Associated Press on Sunday that police have twice questioned his 19-year-old son, Michael, as a witness in the case. Holloway was celebrating her high school graduation with classmates and parent chaperones on Aruba, a self-governing Dutch protectorate, when she disappeared nearly a year ago. Holloway, then 18, was last seen leaving a nightclub in Oranjestad on May 30, 2005, with three others. Those three -- Dutch national Joran van der Sloot, the son of an Aruban judge, and Surinamese brothers Deepak, 21, and Satish Kalpoe, 18 -- were arrested the following month, but released after a judge ruled there was insufficient evidence to hold them. All three have maintained their innocence. |
