Kenneth “Ken” Wayne Mattos, 57, has been missing since sometime in or around 2018, and his family is desperate for answers.

Mattos was released from prison in 2010, and he became homeless at some point along the way. He was living nomadically at the time of his disappearance. However, he always kept in touch with his family. It is out of character for him to go this long without speaking to his sister. The last time his sister heard from him, he was in Malibu, California. His exact missing date is unknown.

Born in Contra Costa, California on June 17, 1964, Mattos and his family moved to Oregon, where he grew up and attended high school. Having lived a transient lifestyle as an adult, he is familiar with many areas, including but not limited to the following:

Eagle Point, Oregon

White City, Oregon

Medford, Oregon

Central Point, Oregon

Malibu, California

Topanga, California

Palm Springs, California

Los Angeles, California

Yreka, California

San Diego, CA

San Luis Obispo, California

Santa Monica, California

Waterford, New York

Upon analyzing those cities on a map and the relationships to each other, it seems like Mattos tends to stay near the coastline in California, even though he has lived in both Northern California and Southern California. It is uncertain if New York is a document error or if he did reside there at some point.

Mattos is described as having dark brown hair with some waves or curls, brown eyes, and a very deep voice.

If you have any clues to Mattos’ whereabouts, please contact the Malibu Police Department at 310-456-6652.
