Seattle's 911 log reports that 20 vehicles have been dispatched to a "Multiple Casualty Incident" at 2514 East Cherry Street, the address of the Twilight Exit bar. Here's the SPD:

At, Casey McNerthney has more: "One man being rushed to Harborview Medical Center was said to have been shot in the left leg. Another victim, a 20-year-old woman, was shot multiple times in the legs. A third shooting victim, a man who was initially said to be a suspect, was shot multiple times in the head." On Twitter, KIRO adds one person is dead and two are injured. (The tip comes via NaFun.)

UPDATE at 11 p.m.: CD News has posted this photo of bar goers being loaded onto a Metro bus. KOMO maintains this police scanner if you want to listen in.

UPDATE at 11:14 p.m.: SPD reports on Twitter that the gunman shot two victims—a man and woman, who do not appear to have life-threatening injuries—before gunman was contacted by officers. The female victim is 25 and the male victim is in his 30s. The Seattle Fire Department reports that the third person was taken to Harborview Medical Center and is "DOA" (it appears clear that this was the shooter, who was fatally shot by police).

UPDATE at 11:30 p.m.: The Seattle Times has interviewed witnesses:

Witnesses, including bar owner Stephan Mollmann, say a man was ejected from the bar after arguing loudly with a woman. About 20 minutes later, he returned with a gun and shot a doorman in the leg and burst into the bar, they said. Once inside, he shot a woman, according to the witnesses.

By all accounts, the gunman was shot by police after leaving the bar.

UPDATE at 11:40 p.m.: CD News reports that the attack began as a domestic dispute. According to SPD deputy chief Nick Metz, "it started as domestic argument btwn suspect and a woman. He then shot her and a bouncer, both not life-threatening," CD News reports. The gunman had fired on officers before police shot him in the alley.
