Description, clothing, tattoos, other identifying markings: A watch and keychain.
Other characteristics: Caucasian male. Brown hair, blue eyes. Zahl has a scar on his right knee. His blood type is A-positive.
Details at time of disappearance: Zahl was last seen in Holmdel, New Jersey on May 12, 1994. He has never been heard from again. His vehicle was discovered abandoned at a train station in Red Bank, New Jersey on May 13, the day following his disappearance. There was no sign of him at the scene. The vehicle had been wiped clean of fingerprints and Zahl's eyeglasses, wallet and credit cards were inside it.
It's possible that Zahl's disappearance was related to a dispute with his brother. The two men were fighting over the family's tree farm. Zahl's brother wanted to buy him out, and he also reported Zahl to the police for growing marijuana on the farm. Zahl's brother has never been charged or named as a suspect in his disappearance, however.
Foul play is suspected in Zahl's case, which remains unsolved.
