PONTOTOC COUNTY, Okla. (KTEN) — A Stonewall teenager has pleaded guilty to a fatal stabbing last year.

Originally charged with first degree murder, 16-year-old Ryan James Campbell pleaded guilty to second-degree murder.

Jaimone Kirkland, 18, was killed at a park in Stonewall on April 18, 2021. His girlfriend rushed him to a hospital, where he was pronounced dead.

"The victim's father and grandmother, they didn't want to have to sit through a jury trial proceeding; they didn't want to relive the killing of their son and grandson," said Pontotoc County Assistant District Attorney Tara Portillo. "It's really sad, because when a 15-year-old is a killer and an 18-year-old is killed, nobody wins."

Campbell was sentenced to 20 years in prison and 20 years of probation.

Jaimone Kirkland was fatally stabbed near Blair Park in Stonewall, Oklahoma, on April 18, 2021.
