DANVILLE, Ky. (WDRB) -- Court documents show 911 dispatchers in Tucumcari, N.M., referred to 15-year-old Jenna Oakley as “a primary suspect of a homicide that occurred in Boyle County, Kentucky” when she was believed to be in the area over the weekend.

Boyle County is where the teenager’s 52-year-old stepmother Rhonda Oakley was found murdered on Sept. 1.

According to Kentucky State Police, Rhonda Oakley’s body was discovered by her stepson when he returned from school to the family’s home near Danville.

A criminal complaint filed on Tuesday reveals investigators tracked Jenna Oakley’s cell phone to a truck stop in Tucumcari, N.M., on Saturday night.

“Officers went to that local truck stop,” said Asst. Chief Peter Rivera with the Tucumcari Police Department. “They didn’t locate anybody, but they had they had the description of the vehicle and the occupants.”

The teenager was thought to be with her 20-year-old boyfriend, Kenneth Nigh -- a man from central Indiana -- in a car stolen from Rhonda Oakley.

"Lo and behold, they happened to pull into one of our motel parking lots. The officer discovered them and put everything together, ran the plate, and it came back stolen. They were the people,” Rivera said.

According to the criminal complaint, an officer asked Nigh “to roll down the window” of the car, but instead he “locked the doors”.

Oakley “was sitting in the driver’s seat” and even “started the vehicle.”

Rivera says the car was eventually turned off, and the couple was arrested in the parking lot of a Motel 6.

Nigh is charged with possessing stolen property and contributing to the delinquency of a minor.

As for Oakley, investigators have not discussed her charges but the complaint says she was taken to a juvenile detention center about 80 miles south of Tucumcari.

The car belonging to Rhonda Oakley remains in New Mexico awaiting Kentucky State Police.

“It has been sealed up and kept here at our facility under watch,” Rivera said. “They want to come down and do some forensic work on it.”

State Police have said Jenna Oakley and Kenneth Nigh have not been charged in Kentucky.
