Matthew Nolan was 21 when he was last seen in Sonoma County, California, on April 14, 1979. He is classified as Endangered Missing and has not been heard from since. At the time he disappeared he was wearing a blue hooded sweatshirt and tan jungle pants. He stood about 6 feet tall, weighed 160 pounds, and had brown hair and brown eyes.

Matthew had schizophrenia, a fact noted by authorities and family that heightens concern for his welfare. Very little is known about his movements or contacts before he vanished, and there is no dental, fingerprint, or DNA information available to assist identification. The Sonoma County Sheriff’s Office remains the investigating agency and asks anyone with information to come forward.

If anyone knew Matthew, saw him in Sonoma County around April 14, 1979, or has information that could help, please share what you know with the Sheriff’s Office.
