31-year-old Nicole VanderHeyden was substitute teacher and mother of three. She lived with her boyfriend and father of her infant son, Doug Detrie, in Bellevue, Brown County, WI. The Green Bay metro area. Her body was found naked and strangled in a farm field on May 21, 2016. Her skull was fractured and she suffered blunt force trauma to the left side of her head breaking and dislocating her jaw as well as injuries to her esophagus, trachea, and neck consistent with strangulation. Her clothes were found off the side of a highway on-ramp. Doug reports her missing that same morning. Police arrest him a couple days later after Nicole's blood is found on the pavement and the murder weapon, a "black cord," outside his home.
