11:28 AM: If you’re heading downtown, do NOT use 4th Avenue South – police have currently closed it at Walker because of a shooting investigation. It’s reported to have happened aboard a Metro bus. Two people were hurt, one from a gunshot wound, the other from injuries attributed to whatever “altercation” happened.
12:11 PM: Street is still blocked as the investigation continues but Pooja emailed us with this advice: “We just went on 4th and it’s possible to go around Lander to 6th to Holgate (and I think still faster than waiting on the West Seattle bridge and I-5 to get to 90).” SPD, meantime, says via Twitter that no suspects are “outstanding” though they haven’t clarified whether that means someone else is in custody or the shooting was done by one of the two people taken to the hospital.
12:28 PM: SFD says the shooting victim is a 51-year-old man and was transported in critical condition; the man with other injuries is 88 and in stable condition. Both were taken to Harborview Medical Center.
1:46 PM: Southbound traffic is now being allowed through. The northbound lanes are still blocked.
ADDED SATURDAY EVENING: According to SPD, the older man shot the younger man, and then fell and hit his head.
