Is Marice Clemmons Dead?

Michael Huckabee's Willie Horton was seriously wounded and may be dead.

"He has suffered a gunshot wound," Troyer said at a media briefing held just before 3 a.m.

Police know that Clemmons was wounded because they have detained other people — Troyer wouldn't say how many — who helped Clemmons after the shootings.

At the briefing, Troyer said police now consider Clemmons a suspect, rather than merely a "person of interest."

Police don't know the severity of Clemmons' wound, and Troyer said he may already be dead.

Update: Tweets from the scene.

Update: Clemmons not in the house. Might be on UW campus.

Update: Big search for Clemmons in Seattle's International District.
