Kenneth John Beltram, 25, was last seen on July 16, 1977, in Brentwood, California. He was with his girlfriend Evangeline Silva and her younger sister Rebecca Rodriguez; the three were reportedly at Brentwood Park that evening and said they were heading to either Oakley or Hogg Island. Later that night they got into Beltram’s pearl-white 1960 Chevrolet with mag rims and a large dent in the tailgate and disappeared.

The next day Beltram’s brother reportedly saw him alone; that sighting is the last confirmed interaction with Beltram. The car was later seen in Concord being driven by an unidentified Caucasian male, and friends who spotted it could not catch up. No trace of Beltram, Silva, or Rodriguez has been found and authorities consider the circumstances highly suspicious.

Does anyone have information about the Concord sighting or remember seeing that distinctive pearl-white 1960 Chevrolet around July 1977?
