The Trevor man who is charged with killing two brothers is going back to prison on an earlier conviction. 25 year old Nathan Kivi allegedly shot and killed 31 year old Kenneth Samuel the Third, and 28 year old Richard Samuel after an altercation at a bar in Twin Lakes on November 24th of last year. He’s charged with double first degree intentional homicide. He had previously been convicted in 2012 on multiple burglary charges. He served two years and was on extended supervision when the murders occurred. Now Kivi is headed back to prison on those charges-for 13 and a half years. Kivi is alleged to have shot the Samuel brothers after an argument which reportedly ended when the brothers threw a bottle at Kivi’s truck. Kivi allegedly responded by stepping out of the truck and shooting the brothers. He’s due back in court in May.
