A former Oklahoma Highway Patrol trooper pleaded guilty Aug. 3 to a federal domestic violence count. Federal prosecutors had charged David Blake Neighbors with entering Indian country to commit a crime of domestic violence. Neighbors, 35, of Hartshorne, was arrested in May after physically assaulting his girlfriend at the tribal complex in Ada, assistant U.S. Attorney Linda A. Epperley said. Co-workers called authorities after he forced the woman to leave and get into his vehicle. Law officers found Neighbors at the woman's home and took him into custody. "Neighbors was on state probation from Pontotoc County on a shoplifting charge at the time of the attack,'' Epperley said. "The fact that a former trooper would commit such a blatant assault in a public place before several witnesses heightened concern that Neighbors was spiraling out of control.'' Neighbors will be sentenced after a pre-sentence investigation. Neighbors could face a possible term of life imprisonment and a fine of not more than $250,000, officials said. A federal judge ordered Neighbors remain jailed pending his sentence. He has been in the custody of the U.S. marshal.
