Norman Lum, 30, of Mill Valley, California, was last seen April 5, 1988, after making troubling statements to his mother and leaving their home. He has not been seen or heard from since. At the time he was described as 5 feet 4 inches, about 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.

The Marin County Sheriff’s Office continues to list the case as open. Few additional leads or public details have emerged, and family and investigators have not announced significant developments. If anyone has information about Norman’s last movements or where he might be now, please contact the local authorities. Could someone who knew Norman or saw him in April 1988 come forward with any details?
