Authorities are searching for a Granada Hills man who was last seen in the Topanga area of the Santa Monica Mountains Aug. 10, officials said Wednesday.
Matthew Weaver was last seen at the Rosas Overlook where he apparently had driven his vehicle.
Hikers said they saw a man who was stuck in the area in his vehicle and they alerted authorities. Weaver, however, was not found in the area after a search.
Another search was conducted on Monday, to no avail, officials at the Los Hills Los Angeles County Sheriff's Department station told KTLA.
James Weaver, the missing man's uncle, said his nephew must have gotten stuck after driving out to the overlook and "has vanished." He said his nephew has not made any phone calls to family members or made any kind of transaction with credit cards.
Missing person flyers can be seen around the area where Weaver disappeared. He recently moved to Granada Hills and is a long-time Simi Valley resident, his brother told KTLA.
Weaver is described by his family as being 5 feet 10 inches tall and weighing about 130 pounds. He was last seen wearing a baseball cap, a T-shirt Dickies pants and red shoes.
Correction: An earlier version of this story incorrectly listed the missing man's city of residence.
