Sydnee Lee Porter, 32, disappeared from Salt Lake City, Utah, in the winter of 1981; the date is recorded as January 1, 1981 but specifics are unclear. She was described as a Caucasian woman with brown hair and blue eyes, about 5 feet 10 inches to 5 feet 11 inches tall and roughly 160 pounds, with a flower tattoo on her left breast. She sometimes used the last name Jacobson.

The last known information places Sydnee with a man named Oscar Baker, who is now deceased; that development has complicated efforts to learn what happened. There has been no contact with Sydnee since she was last seen and no trace of her has ever been found. The case remains open with the Unified Police Department of Greater Salt Lake and is listed in national missing-person databases such as NamUs.

If anyone knew Sydnee, her whereabouts, or her connection to Oscar Baker, please come forward with information that could help resolve this long-standing disappearance.
