Trial has been scheduled for a man accused of dumping a body along a road near Walker last month. Online court records say 36-year old Shaun Hogan of Waterloo on Tuesday filed a written plea of not guilty to a charge of first-degree murder. He’s accused of killing 29-year-old Crystal Marie Gaffney, also of Waterloo. She was the mother of Hogan’s infant daughter. Hogan’s body was found in July in the middle of a road near Walker in Linn County. An autopsy determined that she died of head trauma. Court records show Hogan and Gaffney were involved in a child custody matter. His murder trial is set to begin on Nov. 17.
