Riverside Monster

The Riverside Monster was sighted in 1958 at Riverside California near the Santa Ana River Bridge. The witness was going to cross the bridge before his car was attacked by a reptilian creature. He shook the creature from his car and ran it over. He drove off and reported the incident to the police. It has been sighted since, often closer to the riverbed, and leaves behind a green residue after attacking vehicles.
