WANETTE, Okla. (KFOR) – An Oklahoma woman faces a second-degree murder charge for allegedly running over her husband in an ATV at a campground after a food dispute led to her husband seeking a divorce.

Christopher Lewis’s son Christian Cornett told KFOR a fight between his father and stepmother initially started over food but then escalated.

“He had told her she wanted a divorce and she made a statement that she would overcome him and kill him,” said Pottawatomie County Deputy Sheriff JT Palmer.

The deputy sheriff claims this infuriated Chanelle Lewis, 35, who allegedly jumped on an ATV and shot her for her husband.

“The first thing we ever had when someone intentionally ran someone,” Palmer said.

“That little girl was screaming saying her father was dead!” said a caller on sending 911 from Soggy Bottoms ATV Trails. “Someone ran her father and said he had died on one of our paths.”

Cornett said he hit his stepmother in the face as she allegedly tried to run both him and his teenage sister after hitting their father. The bruise around her eye was still visible on her lap.

“There was some alcohol involved,” the deputy chief said.

Cornett said he is still recovering from the real-life nightmare and he is trying to figure out why the man who loved mega-trucks and mud was gone.

In a statement, Christian said, “He was a great man and would help anyone in need.” He added, “I have 1,000 brothers because he was a father figure to everyone.”

Chanelle Lewis’s charges were initially murder by homicide, but after investigators found new evidence, they were upgraded to second-degree murder. The Medical Examiner’s Office is still searching for the exact injuries that killed Lewis.
