UPDATE: 8:30 p.m. I was completely unaware of the terrible Metrolink accident this afternoon, until our own Nubia contacted me with the news via a text message. Nubia rides the Metrolink daily, but does not commute on this particular train. Zach Behrens and Lindsay William-Ross are running rolling updates at LAist. Kevin Roderick also has extensive coverage of this awful accident at LAObserved, and if you note from Kevin's time stamps on his posts, he's a nightowl and will most likely have updates into the wee hours of the morning.
My employer, The Los Angeles Times, will also continue to keep the online edition of the newspaper updated all night and into the morning.
Lets all say a prayer the death count does not exceed what is currently being reported.
