Prosecutors from Monroe and Lehigh counties have charged 49-year-old Michael Horvath in the kidnapping, death and dismemberment of Holly Grim.
Two witnesses testified in court during Horvath's appearance.
The 41-year-old woman was last seen in Lower Macungie Township in Lehigh County in November 2013. Horvath and Grim worked together at a company that makes church organs.
Horvath remains jailed without bond on criminal homicide and other charges.
Police say they found Grim's bones in Horvath's Ross Township yard during nine days of digging.
