Police are investigating a shooting at Rainier and 52nd. Sounds like one person was injured. More info on the way.

UPDATE: Victim is on the way to Harborview. The shot went through the victim's arm and grazed his chest. Medics have called for a blood run, which means the patient's probably lost a lot of blood.

Update 2: Medics may actually be transporting the suspect. There was also mention of an armored car earlier, but haven't heard anything else that indicates whether this was a robbery or not. There have been a couple of armored car robberies in south Seattle over the last month or two, including one a few blocks away from the scene of this morning's shooting.

Update 3: Our pal @Despeaux is on scene and just Tweeted that this was indeed a robbery. Armored car guard shot the robber four times. In the two other armored car robberies we've reported on recently, no shots were fired.

We've heard the ambulance left the scene without its siren on, and medics were having trouble getting a pulse on the robber earlier. Not good signs.
