A man with light skin and black hair. His eyes dark as the night.

Is it the face of a killer?

You probably remember the crime back in 2004. The case captivated Las Vegas when the newly promoted, spunky 26-year-old was a no-show at her sales job at the Rio Hotel and Casino.

There are nine-and-a-half binders full of carefully gathered evidence. All those facts could never tell investigators the physical characteristics of her killer.

Over a decade later, a new kind of DNA testing is giving LVMPD cold case investigators Dean O’Kelley and his partner Ken Hefner new hope for a break in the murder.

“Someone who has blonde hair, blue eyes we know from what Parabon told us that the likelihood of that being your person is just not possible,” says O’Kelley.

Parabon is a software company that takes DNA data and creates an image of what that person might look like.

Ellen Greytak works at the company.

“Ancestry is the first trait, but then we also predict eye color, skin color hair color, freckling and the shape of the face,” says Greytak.

Back at Theresa’s crime scene in 2004, there was precious little forensic evidence.

The bathroom was stripped clean. No bath mats. Not even a trash…
