Jeffrey Stewart Christian Immel, 33, was last seen February 8, 1989, in Alameda, California. He was on his boat headed toward San Francisco Bay; the next day his boat was found submerged in the bay with no sign of him at the scene. Authorities believe he may have drowned, but his body was never recovered and he remains a missing person.

Jeffrey is described as a white male, brown hair, blue eyes, 5 feet 8 inches tall, about 145 pounds, with scars on his left wrist and right knee and a Timex watch on his left wrist. An investigation and searches were conducted but the disappearance remains unresolved and the case is open.

Did anyone in the Bay Area around February 8–9, 1989, see a small boat or notice anything unusual that could help clarify what happened to Jeffrey?
