Not an extremely high match to today's standards, which is normally in the billions. But the person that DNA came back to was a man in his 30s similar to the composite sketch, and his name was Kevin Pratt.

Then just days before the murder, on August 15th, Kevin Pratt was stopped by police three miles away from the home. This showed he had the opportunity to potentially commit these murders. Investigators would also learn that Kevin Pratt was already in custody on unrelated charges, so building a case against him was the number one priority for the team at Miramar Police Department.

So true, Anastasia. And that's a piece of information you hold back when you interview your suspect and if he's willing to even talk.

Because if he claims that he's never been to the city or is nowhere near the home, and then you can present that back to him, then you're really pushing him in the corner and really potentially giving yourself the real opportunity to determine whether he's being truthful.

The plan was to do a photo array or a photo line for Camille to see if she could pick Kevin Pratt out in a photograph.

You know, it happens more often than you may think. Remember, they do have this DNA, so it would prompt investigators to go past this photo array and attempt to do more work to determine if they had the right person.

Fast forward a few months later, and it's now more than two years after the homicide, investigators tried a different technique, which is a live lineup to see if Camille can pick Pratt out, which encapsulates everything about this case. In a live lineup at the sheriff's office, six individuals walk in. OK, go ahead. You can bring them in. Camille walks in.

She's standing securely behind one-way glass. This is number one. Then each suspect is asked to turn around. This is number two. And face the window. Number three. One at a time. Number four. Turn left. Number five. And then turn right. Number six. This live lineup would produce an answer.

For investigators going into the interview, the strategy should be less is more, holding back on revealing key pieces of evidence you've collected, hoping your subject will independently confirm details only the killer would likely know. Wouldn't it surprise you if I wouldn't identify you? Here, Pratt already has been told, and ID has been confirmed.
