I know they pronounced her in Broward Co., but witness statements seem to indicate she was already dead when the paramedics got there.
And yes, I know they were seen pounding on her chest in front of the hotel, but I'm looking at it from the POV of someone like HKS, who would be looking for loopholes like a defense atty would look for reasonable doubt.
Wouldn't it have to be a pretty big loophole since they didn't want to pronounce her on the scene? Maybe Stern hoped (they would) pronounce on the scene if he drug his heels long enough in calling for help.
