UPDATE at 12:45 p.m. Monday, Oct. 15: Coroner rules death as accidental.
According to the preliminary investigation, the woman lost control of her bicycle after some trucks passed her, and her handlebar hit a parked vehicle, said Sgt. Philip Brooks of the Malibu/Lost Hills Station. She then veered into the bus, and was dragged beneath it and crushed, he said.
The driver was not arrested, Brooks said, but the investigation was continuing.
UPDATE at 9:45 p.m. Saturday, Oct. 13: Metro responds to collision.
MTA spokesman Luis Inzunza told City News Service that he didn't know if there were any passengers on board the bus when the accident occurred.
"I don't know whether the driver was a man or a woman or what the driver's previous safety record was," Inzunza said. "But we are doing our own investigation as well. And I know it's standard policy to give the driver a drug and alcohol test after any accident."
Inzunza said that as of 8:30 p.m., he did not yet have the results of that drug and alcohol test.
UPDATE at 8 p.m. Saturday, Oct. 13: Southbound Pacific Coast Highway is now fully open.
A woman riding a bicycle died Saturday afternoon after colliding with a Metropolitan Transportation Authority bus on the Pacific Coast Highway in Malibu.
The accident took place about 1:50 p.m. at 25019 Pacific Coast Highway, near Puerco Canyon Road, according to the Los Angeles Sheriff's Department. The Los Angeles County Fire Department pronounced the bicyclist dead after arriving at the scene.
"It is too early to verify who was at fault," Lt. Josh Thai of the Los Angeles County sheriff's Malibu/Lost Hills Station said. "Right now we are trying to piece things together and gather witnesses."
Thai said the Metro bus was on duty at the time of the accident. He described the dead bike rider as a 36-year-old female of Latino descent. Her family has yet to be notified. Thai said he was unsure if the woman was wearing a helmet.
Southbound Pacific Coast Highway between Puerco Canyon Road and John Tyler Drive has been closed temporarily.
