Pastor's wife says he was shot and killed by intruder, but police unravel a bizarre threesome tryst that allegedly led to the murder

Police said that they unraveled a coverup by a pastor's wife after she told them that her husband had been shot and killed by an intruder at their home in Ada, Oklahoma.

Kristie Dawnell Evans, 47, initially told police that an intruder had shot her husband, Pastor David Charles Evans, 50, on Monday morning. She called police just after 1 a.m. but Evans died at the scene.

He was the pastor at Harmony Church Ada and had just come home from a mission trip to Mexico.

Ada police then requested assistance with the investigation from the Oklahoma State Bureau of Investigation (OSBI). The woman's story began to unravel when they interviewed neighbors and found that there had been a white Mustang at the home days before the murder. One neighbor provided them with security camera footage of the car.

According to a court affidavit, she confessed her part in the murder of her pastor husband after OSBI agents showed her the video of the white Mustang at her home.

The filing says that she told the OSBI that she had been having an affair with a man after she and her pastor husband participated in a threesome with him at a Super 8 Hotel. She allegedly said that she secreted her phone number to the 26-year-old, Kahlil Deamie Square, during one of their numerous trysts.

She says that she later urged Square to kill her husband after telling him that he had been verbally abusive to her. Square allegedly killed the pastor with his own gun, which was provided to him by Kristie Evans.

OSBI agents arrested both Evans and Square, and charged them both with first degree murder on Thursday.

"This investigation was truly a team effort," said Ricky Adams, the Director of the OSBI.

"OSBI agents from across the state worked tirelessly on this investigation for days," he added. "With the help of OSBI intelligence analysts and multiple law enforcement agencies, the suspects responsible for Evans' murder are in custody. Our team will always follow the evidence and find the truth."
