Summary based on the NamUs case record (MP122880) and 6 other sources
Matthew Nolan, a 21-year-old male, was last seen on April 14, 1979, in Sonoma County, California. Matthew’s case is classified as "Endangered Missing," and he has not been heard from since that day. At the time of his disappearance, he was wearing a blue hooded sweatshirt and tan jungle pants. Matthew stood about 6 feet tall, weighed 160 pounds, and had brown hair and brown eyes. He also had schizophrenia, which adds to the concern surrounding his disappearance.

Very little information is available about the circumstances of Matthew's disappearance. He was last seen in Sonoma County, but details regarding his activities or interactions before going missing are scarce. His family and local authorities have been seeking information that could help resolve the case, but no major breakthroughs have occurred. There is also no dental, fingerprint, or DNA information available for Matthew, which has made identification efforts more challenging for investigators.

The Sonoma County Sheriff's Office is still the primary investigating agency handling Matthew's case, and they continue to encourage anyone with information to come forward. The case has remained unsolved for over four decades, and officials hope that increased awareness might eventually lead to answers about what happened to Matthew Nolan.

Last Seen: Apr 14, 1979
