North Richland Hills police want the public's help in finding a 14-year-old girl who has been missing since Wednesday.
Ruby Contreras failed to return home from North Oaks Middle School in Haltom City on April 24. Police they were notified at 8 p.m. that night of her disappearance.
Investigators said they believe she has left North Texas and could be with 26-year-old Stephan Andrew Cox.
Cox currently faces charges after a teen girl from Pennsylvania reportedly stole her parents car to drive to Ohio to meet him.
Court records show that Columbus, Ohio, authorities in January charged Cox with two counts of unlawful sexual contact with a minor.
Cox, who has been on house arrest since February, was supposed to have an ankle monitor. He is due in court in Ohio on Tuesday.
The Pennsylvania girl's parents told investigators that she and Cox met online.
North Richland Hill police said they do not believe Contreras had met Cox face-to-face before Wednesday but will not say how they met.
Police say Cox is dangerous and that Contreras is not safe with him.
Police believe they might be traveling west by bus service. Investigators have photographic evidence that the pair traveled to El Paso on a Greyhound bus that left from Wednesday from the downtown Fort Worth terminal.
The Contreras family told police that her disapperance is not normal behavior and that there is no reason to believe she ran away from home. The family said she did not take her cellphone with her and that they have never heard of Cox.
Ruby Contreras is 4 feet 11 inches tall and weighs approximately 95 pounds. She was last seen wearing a black hoodie and blue jeans.
Stephan Andrew Cox is 5 feet 5 inches tall and weighs about 130 pounds.
The Texas State Operations Center has refused to call Contreras' disappearance an Amber Alert because of the lack of information on the vehicle they may be traveling in, but North Richland Hills police say they are still working to classify it as an Amber Alert and the classification doesn't lessen the need for the public to help locate her.
The North Richland Hills Police Department is asking anyone with any information as to the whereabouts of Contreras or Cox to call 911 immediately.
