Louis Jason Blumenreich was 33 when he was last seen in North Hollywood, California, on January 14, 1985. He reportedly left his place of employment that day and did not return; his whereabouts have been unknown since then. The disappearance was reported to police on January 21, 1985, and the Los Angeles Police Department’s Adult Missing Persons Unit is the investigating agency.

Blumenreich is described as a White male, 6 feet tall, about 220 pounds, with black hair and brown eyes. Very few other details have been released publicly — there is no information about what he was wearing, any items he may have had, distinctive physical features, or how he was traveling when he left work.

If anyone knew Louis, worked with him, or remembers his movements in North Hollywood in January 1985, please share what you know with the LAPD’s Adult Missing Persons Unit.
