Lewis Schrodt shot Mickey Lobdell in the chest after a domestic dispute near Clearmont, Mo. in December 2013. Lobdell later died.
"Missouri's self-defense and castle doctrine is clear," Rice said in a statement. "You have a right to defend yourself on your property against death or serious physical injury. In this case, Mr. Schrodt acted within his legal right and defended himself."
According to a release from Rice, Schrodt was defending himself and fired two warning shots before firing the fatal shot. According to Rice's statment, Lobdell had been drinking and Schrodt, who suffers from physical disabilites, felt threatened by Lobdell who was threatening and approaching Schrodt when he was shot.
Rice also said Lobdel had outstanding warrants in Kansas and had a history of criminal convictions.
According to Nodaway County Sheriff Darren White, Lobdell was Schrodt's nephew. The shooting happened during a family gathering.
