Overview

• The Pennsylvania Department of Corrections confirmed that Mark Eugene Warfel, 92, died on Sept. 11 at SCI Laurel Highlands in Somerset County.
• State police had named Warfel as a suspect in 17-year-old Tracy Kroh’s 1989 disappearance, though he was never charged in that case.
• Warfel was incarcerated on unrelated indecent assault convictions at the time of his death.
• Kroh was last seen near the Alex Acres Trailer Park in Halifax; her 1972 Mercury Comet was found the next day in Millersburg and her wallet was recovered in 1993 along a creek in Washington Township.
• Investigators say the case remains open with prior searches, including a 2019 property search and a 2023 Mountain House Road demolition, yielding no remains, and they urge tips to Troop H at 717-671-7534 or 1-800-4PA-TIPS.
