Jeffrey Stewart Christian Immel, a 33-year-old man, was last seen on February 8, 1989, in Alameda, California. He was on his boat, headed toward San Francisco Bay. The following day, on February 9, 1989, his boat was discovered submerged in the bay, but there was no sign of Jeffrey at the scene. Authorities believe he may have drowned, but his body was never recovered.

Jeffrey was described as a white male with brown hair and blue eyes, standing 5'8" tall and weighing about 145 pounds. He had distinctive scars on his left wrist and right knee and wore a Timex watch on his left wrist. Despite an investigation and search efforts, his disappearance remains unresolved, and he is listed as a missing person.

His case is still open, and authorities continue to seek information that might provide clues about his disappearance.
