Hey everyone.

Just a quick heads up before we get started. This episode contains

descriptions of violence and sexual assault, so please take extra care when

listening. Karen Falaska told me that in the summer of 2017 she was working in her office in Boulder, Colorado,

and she got a call from the University of Colorado Police Department.

I was at my desk, just a parking lot away from the police department and they were wanting me to come over there.

I already knew in my heart that something was going on

in goodness his case. Karen was nervous. She'd spent almost 50 years hunting for the

man who murdered her sister and she

sensed the truth might have finally arrived but now it seemed like all she

wanted to do was get away from it and I kept saying know what, I can't come out today, I'm just, my back's up against

the law and it deadlines and then they kind of broke down and said, you've got to come.

Bergen County is flying here to tell you something that you want to hear.
