reporter: we got audio the 911 call and the caller was saying they saw the gentleman slapping the girl, brian laundrie and gabby petito. you pair that with what we heard from gabby on that video and she is apologizing saying she can sometimes be mean and she is ocd. what do you think of her putting a lot of blame on herself? that was apparent which was from the beginning she seemed to minimize the incident and take the blame for the incident and that is striking because she appears scared and upset, scared upset young woman, very coherent at times, string a sentence together and keep blaming herself, that fits the profile of domestic abuse victim.
