Kelli Ann Cox
Missing since July 15, 1997 from Denton, Denton County, Texas
Classification: Endangered Missing


Vital Statistics


Circumstances of Disappearance
Cox was last seen at a Conoco gas station at the intersection of East McKinney Street and Railroad Avenue in Denton, Texas on July 15, 1997.
Kelli was a student at the University Of North Texas in Denton, Texas. On July 15, 1997, she attended her morning classes and took a field trip with her criminal justice class to the Denton Police Department. She drove her 1989 Nissan 240-SX to the facility and parked her car in a nearby lot. Cox was not allowed to bring her purse or keys into the facility and she locked her belongings inside of her vehicle. She planned to use a spare key hidden under the vehicle's fender to open the car after the tour.
Kelli discovered that her spare key did not work after the tour dismissed. She walked back to the police department and attempted to call her boyfriend, Lawrence Harris III. Cox was unable to reach him for unclear reasons and officers directed her to a pay phone two blocks away. She reached Harris from the telephone outside of the Conoco gas station and convenience store near East McKinney Street and Railroad Avenue.
Harris arrived at the police department between 12:30 PM - 12:45 PM. He discovered Cox's car abandoned inside the parking lot. There was no indication of her in the area and she has never been heard from again. No witnesses observed her departure from outside the Conoco station.
Cox left all of her personal belongings behind at her family's residence, including $200 in cash. There has not been any activity within her bank account since July 1997. She was devoted to the daughter she was raising and would never leave her behind willingly.
