Summary based on the NamUs case record (MP10182) and 5 other sources
James Vincent Bierman, a 28-year-old man, was last seen on February 22, 1999, in Felton, California. He called in sick to his job at Citizens Utility that morning but was never heard from again. His white truck was found abandoned shortly after his disappearance near the San Lorenzo River, parked at a location where he had previously done emergency pipe repairs. The truck had its keys in the ignition and post-it notes detailing Bierman's tasks scattered on the dashboard. Despite a thorough search of the surrounding area, including the riverbank, no trace of Bierman was ever found.

Bierman lived alone, and several days passed before he was reported missing. Groceries with a receipt dated close to his disappearance were discovered at his home, furthering the mystery. Investigators speculated that he might have slipped in the mud near the river and fallen into the water, but despite extensive searches, no evidence supporting this theory was uncovered. Bierman was described as a 6'3" to 6'4" tall man with dark blond hair, blue eyes, and a scar on one of his shins. His case remains unsolved.
