The case Muller is most known for, as shown in Netflix’s ‘American Nightmare,' happened in Vallejo in March 2015 and involved the kidnapping of Denise Huskins.

Matthew Muller, who is currently serving a 40-year sentence for the kidnapping of Denise Huskins, pled guilty Friday in Santa Clara County court on new charges of medicating and then sexually assaulting another woman.

Matthew Muller was convicted of kidnapping and sexual assault in a 2015 case in which Vallejo police initially accused the victim and her boyfriend of making up the story of her abduction. He pleaded guilty this week in two additional cases.
