PALA MESA, Calif.—A charter bus swerved on a rain-slicked Southern California highway and rolled down an embankment Saturday, killing three people and injuring 18 others, authorities said.
Several passengers were thrown from the bus, and one of the dead was trapped under the vehicle after it landed on its roof shortly after 10 a.m. off Interstate 15 in Pala Mesa, an unincorporated community about 45 miles north of San Diego, North County Fire Protection District spokesman John Choi said.
