Ludwick claimed to have helped Van der Sloot dig up, smash and cremate Holloway's bones in 2010. In February 2018, Elizabeth Holloway sued the producers, alleging this and other claims are fictional and harmfully lurid, and that she was misled into providing a DNA sample for comparison without being made aware of plans for a show. In March 2018, Ludwick was stabbed to death by a woman he tried to kidnap. Investigation criticism The Twittys and their supporters criticized a perceived lack of progress by Aruban police. The Twittys' own actions in Aruba were also criticized, and the Twittys were accused of actively stifling any evidence that might impugn Holloway's character by asking her fellow students to remain silent about the case and using their access to the media to push their own version of events. The Twittys denied this. In televised interviews and in a book, Beth Twitty alleged that Van der Sloot and the Kalpoe brothers knew more about Holloway's disappearance than they have told authorities and that at least one of them sexually assaulted or raped her daughter. On July 5, 2005, following the initial release of the Kalpoes, Twitty alleged, "Two suspects were released yesterday who were involved in a violent crime against my daughter," and referred to the Kalpoes as "criminals". A demonstration involving about two hundred Arubans took place that evening outside the Oranjestad courthouse. The protesters were angry over Twitty's remarks, with signs reading, "Innocent until proven guilty" and, "Respect our Dutch laws or go home." Satish Kalpoe's attorney threatened legal action and described Twitty's allegations as "prejudicial, inflammatory, libelous, and totally outrageous." On July 8, 2005, Twitty read a statement that said her remarks were fuelled by "despair and frustration" and that she "apologize to the Aruban people and to the Aruban authorities if I or my family offended you in any way." In her 2007 book Loving Natalee: A Mother's Testament of Hope and Faith, Twitty wrote that, Following the airing of the De Vries programme on Dutch television, Twitty adhered to the position that the tapes represented the way events transpired and told the New York Post that she believed her daughter might still be alive if Van der Sloot had called for help. She contended that Van der Sloot had dumped Holloway's body, possibly alive, into the Caribbean ocean. Twitty also alleged that the person Van der Sloot supposedly
