Deborah Clark was my step-sister.

She was a kind, gentle, loving, soul.

She also was so much fun.

And she was looking for excitement.

So she goes to Miami. That's where it's at, the lights, the glitter,

the 70s. She had friends. She got an excellent job. She met, you know, a fantastic guy. The world

was hers. And then we get this grand slam phone call. The brutal way that Debbie was murdered.

This was not somebody who came in, shot Debbie, and ran out.

It couldn't have been her boyfriend.

He was in New York.

In a loved triangle situation, his wife was the one that was being scorned.

Debbie's case was the oldest cold case in Miami-Dade County.

We succumbed to the idea that nobody was going to pay the price.

We almost gave up hope.

And then all of a sudden, there's a knock on the door.

There are over 100,000 cold cases in America.

Only about 1% are ever solved.

This is one of those rare stories.

It's August 6, 1977.

Roxanne Yusin lives in Miami, Florida. My sister Debbie was a typical small city girl

that wanted to lead a different life.

She was a nurse.
