"(I saw) my life flashing in front of me before I blacked out," she told the news station, "and he saved my life. He honestly saved my life."
Phillips had a knife in his hand when he turned to look at McWhorter, police said. The trooper pulled out his Taser and demanded Phillips release his weapon and get on the ground. When he refused, McWhorter stunned Phillips and turned his attention to Purvis.
Police said Purvis was treated at the scene and released. Phillips suffered a self-inflicted knife wound. Medics took him to a local hospital.
Authorities charged him with fourth-degree assault, third-degree terroristic threatening and resisting arrest.
Kentucky State Police continued to investigate the case Tuesday.
