A Sapulpa woman was sentenced to 20 years on Thursday for second-degree murder in Indian Country, according to a release from the U.S. Attorney’s office.
U.S. District Judge John D. Russell sentenced Christin Brianna Kelley, 35, to 240 months imprisonment, followed by five years of supervised release.

Shortly after 4:00 a.m. on the morning of January 9th, 2024, Kelley and the victim, Isaac Smith, were sitting in a car in the parking lot of a gas station in Sand Springs. Kelley shot Isaac Smith several times in the head and chest, killing him. Law enforcement recovered the loaded pistol Kelley used in a trash can near the car.
Last November, Kelley pled guilty to Second Degree Murder.
Kelley is a citizen of the Muscogee (Creek) Nation and will remain in custody pending transfer to the U.S. Bureau of Prisons.
The FBI, the Sand Springs Police Department, and the Oklahoma State Bureau of Investigations investigated the case, and Assistant U.S. Attorneys Eric O. Johnston and Stephen Flynn prosecuted the case.
