She also had a gunshot wound to the head.

Her hands had been bound behind her back with an extension cord.

Investigators got their first big break in the case and it came about 40 miles south in Dyersburg, Tennessee.

About nine o'clock at night on the same evening that Sherry and Megan had been murdered, a mother in Dyer County, Tennessee describes coming home with her kids and a maroon van pulls in.

The man walks up and she describes the man pulling a gun from the waistband of his pants and pointing it directly at her.

She tries to start shutting the door on his arm.

That's when he shoots.

The bullet goes through the door and hits her in the shoulder.

She survived and he pulled back out to the van and took off.

The crime laboratory technician was able to match the bullets and say that the same gun was used in both crimes.

So in 1998, we were interviewing suspects that had criminal histories, that had been involved in assaults and sexual assaults and looked similar to the composite that we had posted on the media.

Nothing worked.

Our hope was when we submitted this profile, it would send us a name back

of a suspect that had been arrested in the past.

In South Carolina in April of 1990, a young woman named Genevieve Zitricky was found murdered in her apartment.

Jenny was 28 years old.

She had been strangled.

She had been sexually assaulted.

When I arrived at a crime scene, there was blood everywhere.

Jenny's body was in a bathtub with her hands behind her back.
