California oil spill may have been caused by a ship's anchor: The pipeline was "pulled like a bow string"

Long Beach, California — A ship's anchor may have hooked, dragged and torn an underwater pipeline that spilled tens of thousands of gallons of crude oil into the ocean off Southern California, according to federal investigators who also found the pipeline owner didn't quickly shut down operations after a safety system alerted to a possible spill.

Questions remained about the timeline of the weekend spill, which fouled beaches and a protected marshland, potentially closing them for weeks along with commercial and recreational fishing in a major hit to the local economy.
