Matthew Jonathan Weaver Jr., 21, of Simi Valley was last seen August 10, 2018. Surveillance captured him that morning driving a silver BMW on the Topanga Tower Motorway toward Rosas Overlook in the Santa Monica Mountains. Around 11:55 a.m. he sent a text saying something crazy was happening and that he wanted to talk while he had the chance; that was his last known communication.

His BMW was found abandoned near Rosas Overlook the following day. Searches in the area turned up personal items including his car keys and a torn t-shirt near the vehicle. Friends say he had suffered a head injury shortly before his disappearance, and hikers later reported hearing calls for help around the time he went missing; the family believes foul play may have been involved. The Los Angeles Police Department is investigating and the family is offering a reward for information.

If anyone saw Matthew near Rosas Overlook or has information about his whereabouts, please share what is known with investigators.
