BERMAN: We're now learning that a loud noise may have triggered the police shooting in Minnesota that left an Australian woman dead. The officer who was behind the wheel says something near the cruiser startled him.</s>HARLOW: We still haven't heard from the other officer, the one who fired the shot that killed this woman, Justine Ruszczyk. He's at this point refusing to speak to state investigators. But chilling new audio is revealing more about that deadly encounter.</s>UNIDENTIFIED MALE: Female screaming behind the building. Shots fired. Can we get EMS code 3 Washburn and 51st Street? We got one down.</s>HARLOW: Our Scott McClain is in Minneapolis following all of the developments. So, this officer is not saying anything.</s>SCOTT MCLEAN, CNN CORRESPONDENT: Yes. That's right, Poppy. We are starting to get more of a picture of what happened to Justine Ruszczyk in this alley but it is far from a complete picture. The problem here is there's no dash cam or video. There's no body cam or video. And as you say, the officer who pulled the trigger, Mohamed Noor, is refusing to tell his side of the story. But we are hearing from his partner, Michael Harrity, says the two were driving down this alleyway late Saturday night with their squad car lights off when suddenly he heard a loud noise. The next thing you know, Justine Ruszczyk is at the driver's side window, that's when Mohamed Noor shot her in the abdomen from the passenger side. The two attempted CPR to resuscitate her but ultimately, that was, of course, unsuccessful. Now, why was that shot fired? Well Mohamed Noor's lawyer -- hasn't given any indication as to whether his client will ever say that publicly or whether will ever do an interview with investigators.
