What's up? HANDS UP. GET ON THE GROUND. GET ON THE GROUND. >> RIGHT NOW YOU'RE BEING you're being held and arrested for suspicion of being involved in a homicide. And what homicide is that we're discussing? What what do you think I did and who is this person and if you can answer those two questions, that would be awesome. What do you think was found in the trunk of that vehicle? I'm not sure what was in there. There was a dead body in the trunk of that car. A dead juvenile body. Really? And who was it? The reason why we don't know who it was is because the head was missing. What? In my car? Shortly into the interview, Julissa refuses to even accept that she was driving with a child's dead body and blood in her car. Do you have any kids? I have a son. You have a son? How old is your son? Um six. Six years old? Yeah. What's your son's name? Eli. Can I go home and check on my baby and check on my house and everything? Still, Julissa fails to explain how a child's dead ended up in her car. But what she doesn't know is that officers have reviewed CCTV footage from the night before the discovery, which shows Julissa at 11:22 p.m. walking out of the garage with her son Eli, then placing him gently in the back seat of her car. This is the last time anyone saw the six-year-old boy alive. But then Rob mentioned something that could prove to be the missing link. She killed him. I know she did. How do you know it? I just know she did. I just know I know for a fact that she did. In the autopsy report, it's confirmed that the dead body is that of Eli Hart. He was shot around nine times, likely while he was helplessly strapped in the car. Authorities also learned that Eli was pre-lingually deaf. Even while acting to show remorse, Julissa's already preparing another excuse to distance herself from the crime. Did you find the people who did this? A lot of his a lot of his head brain tissue cuz we think He was the most important person in the world. cuz we think he deserves that. He deserves everything. I really do love him, but I want you to know that this baby boy is the most important person in the world to me. I would never hurt him. I would never do anything to him. I protect him. You have to believe me. This is my baby boy. Their shirt from her cell records that Julissa drove her son to Lake Minnetonka Park where she ruthlessly shot Eli nine times while he was strapped in his child safety seat. But the investigation that follows regarding Eli's earlier childhood leaves everybody speechless.
