Summary based on the NamUs case record (MP11808) and 2 other sources
Norman Lum, a 30-year-old man from Mill Valley, California, was last seen on April 5, 1988. On the day of his disappearance, Lum made troubling statements to his mother before leaving their residence. He has not been seen or heard from since. At the time, he was described as being 5'4" tall, weighing around 140 pounds, with brown hair and brown eyes. He was last seen wearing a rust-colored velour shirt, navy blue corduroy pants, and brown shoes.

Despite efforts by law enforcement and his family, few details have emerged regarding Lum's disappearance. The case remains open, with the Marin County Sheriff's Office overseeing the investigation. Authorities have not provided much additional information, but the absence of significant leads has made this case a haunting mystery that has lasted for decades.

Anyone with information is urged to contact the local authorities, as Lum's whereabouts remain unknown to this day.
