Ellen Greytak, the director of Parabon told the I-Team they use DNA and a computer program to generate a sketch of what Lisa Ziegerts killer could look like. She said while phenotyping has created nearly identical images in the past, the service also has its flaws. That person's age, their weight, how they wear their hair, whether they've gotten tattoos, none of that is going to be in the DNA, and it does really affect how you interpret person, she said.
DA Gulluni told the I-Team the composite sketch of Lisas killer has already helped them narrow down suspects in their investigation. It allows investigators to really exclude people as a matter of fact. For instance, we can exclude people from Asian ascent, or Latinos because we know the person is from a Caucasian background, 50% from Northern Europe, and 50% from Southern Europe, he said.
Gulluni believes Parabons sketch could be the break they've been looking for, for the past 24-years, and Dee Ziegert agrees. This will be the thing that will bring justice for Lisa. Will it bring Lisa back? No, but we think it might give her a good sense of peace, she said.
