Here is my interpretation of the 911 call. It's pretty clear to me....he is running his words together, but i am pretty sure it's close.
9-2013 050 and 38 seconds
911: 911 emergency
BL: Yes, I'm in the middle of a field. In fact we just pushed some guys over, right here going towards Abilene on both sides. My truck ran out of gas. Theres one car here and a guys (guy is) chasing me in the woods. Please hurry!
911: Okay, now run that by me one more
BL: And when I was talking to em I totally like ran into em
911: Oh, you ran into em, okay.
BL: Yeah-I got the first guy
911: Do you need an ambulance?
1st Guy: Yes. (totally out of breath or BL is sitting on his chest)
BL: No, I need the cops.
911: Okay. Is anybody hurt? Hello? Hello? Hello?
Here at the end I think Brandon did not answer because he was trying to be quiet because he heard someone coming. Just my opinion here tho.
