The murder of Kelsey Berreth: What does Krystal Lee know about the Colorado mom's killing?
Text:
"Still, there are unanswered questions. Initial forensic tests at Kelsey's home revealed some of her blood was mixed with unknown female and male DNA.
Aya Gruber: The key is that male DNA did not belong to Patrick Frazee.
Nikki Battiste: Do we know whose female DNA that is yet?
Aya Gruber: We don't yet.
Nikki Battiste: And to this day there is no body and there is no murder weapon. What's that mean for the prosecution?
Aya Gruber: I think it makes it a much more difficult case … The cell phone evidence tells a story. And that's very helpful. But it can't tell a full story. … So, what this case lives and dies on is the testimony of Krystal Lee. … That is the connective thread for everything."
