Muller worked as an undercover police officer in New York. In his personal life, he was married to a woman named Molly and had two sons with her. He went undercover in the bank robbery world in a stint to capture Dale Schrader, who robbed fourteen banks from 1994 to 1997. Little details were revealed about the case, but Muller somehow became associated with Schrader. He was eventually able to provide evidence that helped put Schrader away after he was sold out by fellow bank robber Dan Otey. Afterwards, Muller moved on with his life, unaware that Schrader deduced he was a cop and that he was plotting a revenge scheme against him. Things came to a head-on December 14, 2009, when Schrader suddenly approached him at a hardware store parking lot, showing him a photo of his family being held captive and claiming to know where they are. He forced him to drive over to a poor neighborhood, where Muller witnessed him murdering a crack addict named Stacy Ryan. He then reluctantly drove Shrader to an empty field, where he disposed of Ryan's body. Next, the two engineered a scheme to break Schrader out of police custody in case he was captured while abducting his daughter Jenny.
