11:27 AM: Appeal reader Kenny lets us know that a Muni accident just happened at Mission & Beale, saying that it “looks like someone is trapped under a bus, with 2 14-Mission vehicles involved.” From his IMs to the Appeal:

They’ve got stretchers out, and they’re on hands and knees trying to get to whoever is under the bus.

They’ve taped the area off with yellow tape, moved onlookers out, and now have brought blankets off to block off the view between the buses. I think someone may have died.

OK, the blankets are down and the person has been loaded into a waiting ambulance. It has now sped away.

They’re still looking under the bus. I’m not sure if there’s someone else down there, or what. There is not another ambulance on the scene, though, so maybe they’re just trying to figure out what went wrong.

No other victim, apparently. They are picking up their equipment and going back to the fire trucks. Police seem to be taking over the scene now.

I’ve emailed the SF MTA for confirmation, and will update when I get a response.

11:39 PM: Kenny updates us, saying that

They just moved the tape back to the 2 buses, and the last fire department vehicle just left the scene. The police still have the whole block of Mission closed off, though. Unless they have a way to reroute around the scene, I’d guess the 14-Mission line is going to be backed up for a while.

11:45 AM: The SF MTA’s issued an alert to media, saying that at around 11 this morning, there was “an accident at Mission and Beale streets involving a 14 Mission trolley bus and a 14 Mission Limited bus and a bicyclist.” The MTA does not give any other details on the circumstances of the accident or the extent of the cyclist’s injuries.

They say that bus service is disrupted, and that “the 14 Mission route is switching back at 4th Street. The 14 Mission Limited is routing around the scene from Main Street to Market Street to 4th Street and back to its regular route on Mission Street.”

The Appeal has left messages for the SFFD for more details on the victim, we’ll update when they respond.

11:54 AM: Bay City News confirms, after speaking with SFFD Lt. Mindy Talmadge, that the victim, a man, was indeed trapped between a bus near Mission and Beale. She told BCN that crews were “sent to the scene to try to lift the bus to extricate the victim,” but at the time of their report she did not know the victim’s condition.

12:18 PM: According to KCBS says the victim “is or was reportedly suffering from extremely critical injuries” (the story’s since been reedited to say “life threatening injuries”).

12:30 PM: Bay City News confirms previous reports of the circumstances surrounding the incident, saying that after the 10:59 AM accident (what happened? We still don’t know):

“Emergency responders had to crawl under the bus to access the victim. Crews lifted the bus, and the victim was quickly extricated and taken to a hospital,” where he’s said to be suffering life-threatening injuries, according to an SFFD spokesperson.

1:19 PM: SFPD and the SFMTA are reportedly trying to figure out how the victim ended up trapped under the bus. The victim, whom SFPD spokesperson Lt. Lyn Tomioka says was not, as reported by the MTA, a cyclist, was apparently walking in a lane of traffic on Mission Street when he was pinned between two buses and run over by one.

No word yet on the condition of the victim. We’ll keep you posted.

4:16 PM: SFPD spokesperson Lt. Lyn Tomioka says that the man who was pinned between two Muni buses then run over by one was pronounced dead at SF General at 11:46 this morning.

Police are not yet releasing the man’s identity, and video of the crash taken from the Muni buses is being withheld pending further investigation, according to Tomioka.

The drivers of both Muni buses have been placed on non-driving status and tested for drugs and alcohol, per normal procedure, according to Muni spokesman Murray Bond.

Muni service was back to normal this afternoon after being rerouted for a few hours after the incident, Bond said.
