In Wichita Falls, Texas, police had four unsolved murders,

Her car was found abandoned on a deserted road, not far from the hospital.

There were no foreign fingerprints or clues inside.

Four weeks later, a Texas electric worker found Tony's body

Almost immediately, police had a suspect.

Twenty-four-year-old Danny Laughlin was seen riding his motorcycle
