Did Dee Dee ever mention specifically which direction TM went, towards home or not? Did TM ever say I am running or walking any specific direction?
No, unless 'from the back' is such an indication.
I'm not sure where you believe TM was
I have no idea where he was. Why would you assume I have an opinion on that?
when he said he was right by his fathers house
The first time Dee Dee said 'right by', it was 'right by his dad's' . De la Rionda misunderstood that as 'right by his a*' (8:44-50
). (The 'd's are audible, but barely. I missed them the first time too.) So Dee Dee told part of the story over, and substituted 'right by his father's house'. Clearly she was paraphrasing.
If Dee Dee is telling the truth or something close to it, Trayvon told her something that she paraphrased as 'right by his dad's'. She responded by suggesting that he 'keep running to his daddy's house'.
There's a bit of evidence, which I've previously overlooked, that for Dee Dee 'right by his dad's' did not mean he was at the back door. She would hardly suggest that he run to it if she thought he was already there.
As Dee Dee represented herself, I think it's clear she was not of the opinion that Trayvon should turn around and run back the way he came.
