The Murder of Brianna Denison
On November 1, 2008, the Reno Police Department received a report from an anonymous caller through the Secret Witness tip line that a man by the name of James Biela, 27, was exhibiting strange behavior and fit some of the suspect criteria that police had developed in the various cases over the past year. Detective Adam Wygnanski was assigned to follow up on the tip, and met with Biela on November 7.
Although Wygnanski determined that Biela was the registered owner and frequent driver of a 2006 4-wheel-drive Toyota Tacoma pickup truck with an extended cab, with gray colored interior, during the timeframe of the sexual assaults and Brianna's disappearance. Biela denied having anything to do with Denison's murder, and he claimed that his girlfriend, who was also the mother of his child, would provide him with an alibi for his whereabouts at the time of Denison's disappearance. Wygnanski, lacking physical evidence that would ensure a conviction, had little choice but to let Biela go.
