I doubt he impersonated a police officer....In WV, several crimes are included in all inside the same code section.... obstructing, resisting and fleeing are all the same charge....I'd say it's just listed in the court as, lying to a wvsp/impersonating a wvsp....
Totally guessing, he may have gave a false name when he was stopped...probably will be charged as, providing false info to a WVSPO....
