Several news outlets, the police scanner, and people on Twitter report that a truck has seriously injured four pedestrians on 1st Avenue South. One person tweeted this photo of the truck. KOMO reports that medics have called for a blood run for the victims.

The accident occurred in front of Showbox SoDo, which is right next door to the building where this pot forum was held earlier this evening. No word yet on whether the victims where attending the Ingrid Michaelson concert at the Showbox, the forum, or were in the area for another reason. The scanner indicates the road has reopened to traffic.
