Burkett was in the middle of a bitter custody dispute with Andrew Beard, the father of her 1-year-old daughter. On the day of the murder, Burkett's mother, Teresa Collard, is heard on police body cam video recalling something Burkett said about Beard, "… She even said, ‘I think he's the kind of person that's gonna try to kill me,' and he did. And he did. Oh my God." The all-new episode explores how the investigation quickly zeroed in on Beard. Carrollton Police detective Jeremy Chevallier recalls that the case took a clear direction from the start. "Within an hour of getting to the crime scene, we knew that we had needed to look for Andrew Beard," he says. But as it turned out, Beard was only the beginning of this complex story. Over the course of the investigation, detectives uncovered a twisted plot involving Beard's new fiancée, Holly Elkins. Police came to conclude she was the mastermind.
