MADISON, Wis. (AP) — A divided state Supreme Court has ordered a new trial for a man convicted of killing his brother-in-law after he allegedly discovered child pornography on his computer. A jury in Walworth County convicted Alan Johnson in 2017 of first-degree reckless homicide in connection with the shooting death of his brother-in-law, Ken Myszkewicz. Johnson argued that Myszkewicz attacked him moments after he found the pornography on his computer and the jury should have been instructed on self-defense doctrines. The Supreme Court sided with Johnson in a 4-3 ruling
