The man who shot and killed ex-NFL RB Joe McKnight has been found guilty of manslaughter and now faces up to 40 years in prison.
Ronald Gasser, 56, learned his fate today in a Louisiana courtroom ... not far from where he gunned down McKnight during a road-rage incident on December 1, 2016.
Gasser's attorneys filed motions that McKnight was the aggressor, and their client was acting in self defense when he fired off 3 shots.
The jury took just over 7 hours to deliberate the verdict.
McKnight was only 28.
