SAN BERNARDINO, Calif. (AP) — A crash on the main route between Southern California and Las Vegas has injured two people — including a CHP officer— and sparked a 10-acre brushfire but no homes are threatened. It happened Saturday afternoon in the Cajon Pass on Interstate 15 northeast of Los Angeles. Della Miller tells KABC-TV she was on a charter bus heading to Las Vegas when a motorcycle cut in front and crashed. A CHP officer tried to help the rider but an oxygen tank she was using exploded. Miller says the officer had burns to her arms and face.
