They have said her car was nearest to Washington and 22nd. that is a home-lined street and there are homes whose backyards back up to the river. It really doesn't make a lot of sense at this point. That is a LONG way to run or walk (while leaving your car running with your purse in it) It was broad daylight, she wasn't stumbling along in the dark, I would think someone saw something. I wish LE would officially release whether or not people saw her and if she was alone, etc. I fail to see the reason why they are not.
The suicide part doesn't really make sense because why leave her car there? There are roads leading directly back to the river, why park and walk a whole block?
Another thing no one has said, her car was on a main thoroughfare...whose to say somebody ELSE didn't see her car parked there and THEY turned on the hazards so as not to have accidents occur? Somebody called in that her car was there..for some reason, everyone is assuming that SHE is the one that turned on her hazards..I'm thinking she did not.
