On June 9, 2005, Van der Sloot and the Kalpoe brothers were arrested on suspicion of kidnapping and murdering Holloway. Aruban law allows for arrest on serious suspicion from investigators; to continue holding the suspect in custody, an increasing evidentiary burden must be met at periodic reviews. According to Dompig, the focus was on these three suspects from the "get-go". Dompig stated that surveillance of the three began three days after Holloway was reported missing, and included surveillance, telephone wire taps, and even monitoring of their e-mail. Dompig indicated pressure from Holloway's family caused them to stop their surveillance prematurely and to detain the three suspects. On Monday, July 4, following hearings before a judge, Deepak and Satish Kalpoe were released, but Joran van der Sloot was detained for an additional sixty days.
