Sounds like a made up story to me. She had better hope there are two sets of tire tracks on the dead guy’s clothes.
Typically there are more than 2 sets of tracks ~ sometimes 10, maybe 20. Depends on where and what time of day.
Last thing you want to be is a pedestrian on an Interstate.
I’d like a lot more info on her car’s condition before I could begin to assess her her story. She had plenty of time to sober up and get her story straight.
......Sounds like a made up story to me.....
actually it is a well worn plot on CSI where a Muslim Cabbie was beaten by gang members after he ran over a dead man.
