I caught that too. There was no car in front or in the driveway...I wondered if there was an alley behind Travis's house? Was that ever discussed? Where did she park the white car with no plates on the day she snuck up and murdered him?
We had a stalker for many years. Sometimes we discovered where he parked. (he had several hidden spots) as well as using a taxi at times. Anyway, IMO Jodi had cased the neighborhood, knowing the places to go undetected.
Thats my "lived it victim" opinion.
