No charges will be filed against a Greyhound driver involved in a bus accident that killed three passengers last November in Santa Maria, Santa Barbara County prosecutors said Wednesday.
Examining the results of medical tests, the prosecutors concluded that the driver, Samuel Bishop, 63, may have suffered a seizure before his bus swerved down an embankment and hit a tree near U.S. 101, Deputy Dist. Atty. Mag Nicola said.
"There's a strong possibility of a seizure-like disorder that had been previously undiagnosed and unknown to Mr. Bishop," said Nicola, declining to elaborate on Bishop's medical evaluation.
Shortly after the accident, California Highway Patrol officers said that Bishop may have fallen asleep at the wheel.
"We based that on physical evidence," said Officer Gus Lopez, a CHP spokesman in Santa Maria, adding that the bus had drifted off the roadway as though the driver had nodded off.
