In May 2016, thirty-one-year-old mother of three, Nicole VanderHeyden, was found dead. It was apparent she had been murdered due to the state of her injuries. Nicole, who went by Nikki, disappeared after a night out with her boyfriend and other friends. The authorities immediately began looking at Nikki's boyfriend.
Join Mike and Morf as they discuss the murder of Nikki VanderHeyden. Nikki's boyfriend, Douglass Detrie, could have very well ended up spending the rest of his life in prison. The Fitbit he was wearing told the story of his whereabouts the night Nikki was murdered. This allowed the police to shift focus and find the real killer.
