The diver in this case, Therese Schick Knowles, never regained consciousness and died in St. Joseph's about a week later.
I was friends with Terry since elementary school, some 49 years. She came to Australia where I now live, and spent a week on a live-aboard on the Great Barrier Reef a couple years ago. She was also a 30+ year Special Education teacher at the Clover Park school district.
There are lots of unanswered questions about this "accident", especially since Terry had been diving in the Puget Sound for some 20 years. There is a huge conflict between the police report and her "dive buddy" about whether or not Terry was wearing a buoyancy compensator. Terry owned a BC and since she was dry suit certified she was well aware of the need for this equipment. Not only is this fact in contention, if she WAS wearing it, why did it not function as intended? The reports from the scene indicate that she was first spotted "fins out" of the water.
I've attempted to determine what dive shop she was affiliated with because she wasn't filling her own tanks. Everyone seems to be shut-down on where she was going.
Pierce County Medical Examiner Clark (tclark@co.pierce.wa.us) seems to be content to put this into the "never mind" pile instead of fulfilling their charter which says "The public deserves to know what hazards and events are causing sudden and unnatural deaths in their communities”.
There were dozens of people nearby when the accident first was reported and I would guess someone with photos or video on the smartphones.
It's important to determine what exactly went wrong, for the good of the community as well as her friends and family.
