U.S. District Judge Gregory K. Frizzell sentenced Tre Robert Allen Ackerson, 30, Webb City, Missouri for Murder in the Second Degree. Judge Frizzell ordered Ackerson to be sentenced to 600 months of imprisonment, followed by five years of supervised release.

“I hope the family of Ms. Campbell can find some sort of healing knowing the person who murdered their loved one will likely die behind bars,” said U.S. Attorney Clint Johnson. “The Justice Department will continue its relentless efforts to seek justice on behalf of missing and murdered Indigenous people.”

According to court documents, Ackerson kidnapped and violently murdered Jolene in July 2020. The victim’s body was found in a remote field in Mayes County. The investigation showed that Jolene was robbed and kidnapped in Missouri and driven into the State of Oklahoma, where she was murdered by Ackerson.

Various assaults on witnesses took place that included witnesses being kidnapped, restrained with zipties, blindfolded or having their eyes duct taped shut, being shot at, and being beaten.
