A convicted felon with an arsenal of guns faces aggravated assault charges after he allegedly threatened to kill his girlfriend and himself.The suspect, Jonathan Kent Curtis, 34, is charged with aggravated assault and possession of a firearm by a convicted felon. He has waived his right to a preliminary hearing and his case will be heard by the grand jury.The assault allegedly happened at McMinnville Inn where the couple was staying at the time.“Mr. Curtis grabbed her around the throat and choked and punched her with his fist,” McMinnville police officer Marty Cantrell said in his felony warrants against him. It is now considered a felony if there is choking involved in an assault.The victim revealed Curtis had brought several guns to the room earlier that morning despite the fact he is not supposed to have possession of firearms due to being a convicted felon.“He threatened to kill her and himself while holding a pistol,” Cantrell revealed.Police found four guns and ammunition during a search of the room after the complaint was filed.
