WSB photojournalist Christopher Boffoli is at the scene at California and Oregon (map); he says one car hit three others, and adds: “The driver is being taken to Harborview. Police said that there were no signs of alcohol use but that the man was having trouble answering basic questions about what happened. Traffic at Cali and Oregon is backing up a bit but SPD is waving through the rubberneckers.” 1:37 PM UPDATE: Added photo by Christopher, who updates that police say the red car was heading eastbound and crossed into the westbound lane, hitting at least two cars.
