We obtained the sample on a Sunday, and by Friday, we had a report saying that it was a match.

Finally, after more than two decades, you finally have a DNA match.

Yeah.

What was that like?

I mean, it's always a huge sense of satisfaction when you can finally say, oh, we solved it.

We know who did it.

For detectives, there was no longer any doubt.

Eugene Gligor had killed Leslie Prier.

The DNA proved it.

The news spread to the county prosecutor's office.

State's attorney, John McCarthy,

The lead prosecutor, she literally was jumping up and down.

My God, we got a hit on this case.

If you put two years of your life as an investigator and as a prosecutor into building probable cause for an arrest, it's a pretty joyful moment to realize you've got your guy.

Being able to give that answer to the entire family, to Lauren, and to clear her dad's name is huge.

It was just really satisfying on multiple levels.

But before Detective Augustin could share the news with Lauren and with the world, there was one more thing to do.

Put your hands on your back.

With Eugene Gligor in custody, detectives finally have the opportunity to talk to him face to face and confront him with what they had found.

It's an interrogation unlike any other.
