James Vincent Bierman, 28, was last seen February 22, 1999, in Felton, California, after calling in sick to his job at Citizens Utility. His white truck was found abandoned soon afterward near the San Lorenzo River at a place where he had performed emergency pipe repairs. The truck contained the keys in the ignition and post-it notes detailing his tasks on the dashboard.

A search of the surrounding area, including the riverbank, turned up no trace of Bierman. He lived alone and was not reported missing for several days; groceries with a receipt dated close to his disappearance were later found at his home. Investigators considered the possibility he slipped in the mud and fell into the river, but searches produced no evidence to support that theory. Bierman is described as 6 feet 3 inches to 6 feet 4 inches, dark blond hair, blue eyes, with a scar on one shin.

Does anyone who knew James or worked in Felton in February 1999 have information that could help explain what happened?
