Natalee Hollaway's mother said Saturday she believes ``we are going to get answers'' in the nearly three-month-old disappearance of the vacationing U.S. teenager after the arrests of two brothers who were previously detained and released in the case. Satish and Deepak Kalpoe were arrested Friday on suspicion of involvement in premeditated murder and rape of the 18-year-old honors student, Aruba's prosecutor's office said. The Surinamese brothers were arrested after new evidence emerged, the office said, without elaborating. ``I was pumped up at the news,'' Beth Holloway Twitty told The Associated Press by telephone from her home in Birmingham, Alabama. ``The strongest thing I felt was that we are going to get answers.'' Holloway Twitty said she didn't know what evidence authorities had on the brothers but said their re-arrests seemed to support the family's suspicions. Holloway Twitty said she didn't know what evidence authorities had on the Kalpoes but called their arrests a vindication for the teen's family, which was angered by a judge's decision in July to release the brothers for lack of evidence linking them to the teen's May 30 disappearance. The prosecutor's office also said the Kalpoes were suspected of other offenses, but they did not provide details. No details were disclosed about a third man who authorities said was arrested Friday with the Kalpoes. Holloway, of Mountain Brook, Alabama, was last seen leaving a bar with the Kalpoe brothers and van der Sloot on the final night of a high school graduation trip to the Dutch Caribbean island. Extensive searches of the island have produced no sign of the teen, Guardian reports.
