We turn now to a newly released 911 tape from ha while case in New Mexico when a state trooper fired on a minivan driven by a mom and her five kids. An exclusive look at what was going on inside the car from Ryan Owens. Where are you at? Where are you at? Reporter: They are the sounds of sheer terror heard for the first time in an ABC news exclusive. They're chasing us. They're starting to kill us. Okay, I cannot understand you, hon. Calm down. Reporter: Voices from inside the minivan full of five children, New Mexico police were chasing back in October of. Get out of the vehicle right now. Reporter: Officers say the driver, their mom our Rihanna kept fleeing when when they stopped her for speeding. You're where? Reporter: The traffic stop escalated fast. Police say her 14-year-old son scuffled with them and that they had to bash in the minivan's tinted windows just to see what was going on inside. When Farrell took off yet again veteran officer alias Montoya fired three shots at the minivan. In an exclusive interview he told me those tinted windows prevented him from seeing any kids inside. When you found out that there were, in fact, children in that minivan, what did you think? My heart sank. I couldn't believe there was that many children in there. Reporter: Montoya was fired but recently reached a settlement with state police. As for Farrell she's charged with child abuse and fleeing from officers. She's pleaded not guilty and says she ran from cops to protect her children. Her trial is scheduled for later this year and this 911 tape -- They're chasing us. Reporter: Is expected to be a key piece of evidence. For "Good morning America," Ryan Owens, ABC news, Los Angeles.
