Personally, I think part of her bottom lip is missing. If you look at the picture she appears to have full lips - and the bottom lip looks only half swollen...the swelling seems to stop impossibly abruptly. I think its hard to see if she has scratches and other injuries due to the picture. It looks like they tried to make her as presentable as possible - its difficult to even tell that she has the older scar on her face due to the lighting.
Neither of the new composites look too much like she does in the original morgue picture, but maybe that's just me.
I wonder if the site has a standard set of "causes of death" and they put undetermined because there's no "complications from being pushed out of vehicle". (It would make sense for them to have streamlined a form for posting these cases online.) Or they could just be withholding it until she's identified. Or it could be that she died from something they aren't sure wasn't a previously existing condition or something that was a direct result of the accident and they're hoping to find that out when she's identified. The possibilities are practically endless. =(
I keep editing argh! I also just thought that maybe since they don't know if she jumped or fell or was pushed they don't know if they can label it a sucide or an accident.
