Well, there it is...a tiny mention on a blog. Thanks for the Fire CAD tip. I had forgotten about that.
I-5 fall: Seattle Police were investigating after a woman was reported to have jumped from the Madison overpass and was struck by a vehicle on I-5 late on the night of Friday, June 26th. According to police radio dispatches, the woman had been reported distraught and had been talked from the ledge of one overpass by a 911 caller earlier in the night. CHS has not yet verified if the woman survived the incident.
