In August 2014 Nigrini published an article, "Lessons from an $8 million fraud", with Nathan J. Mueller who stole $8.45 million from his employer, an insurance company, over a four-year period. In the article Mueller describes his fraud scheme, how he explained his newfound wealth in the form of expensive cars, watches, nightlife entertainment, and Las Vegas gambling trips, to his wife and friends, and ultimately how he was caught. Mueller served his sentence at Federal Prison Camp , Duluth, a minimum security federal prison. He was released on February 27, 2015. In the article Nigrini reviews the preventive and detective anti-fraud measures that could have detected the multimillion-dollar fraud four years before it was detected, and only by chance. Nigrini and Mueller won the Lawler Prize for the article in 2014.
