Mark Sheridan Waden, an accused killer, tells police that his girlfriend disappeared after he says she was involved in “hidden secrets,” according to reports from multiple outlets. The girlfriend is described as a US citizen and former beauty queen. The accounts state that Waden links her disappearance to a threat he made to immigration officials. In the reports, Waden alleges that after he threatened to report her to immigration authorities, she went missing. Police and investigators are treating the case as a disappearance that is connected to the allegations now before the courts. The outlets do not provide additional confirmed details about the claimed “hidden secrets,” the nature of the alleged immigration-related threat, or any independently verified evidence within the excerpts. The reporting is consistent in identifying Waden as the accused, describing his girlfriend in the same terms, and stating that his explanation to police centers on events that followed his alleged threat to immigration officials.
