You read opinions about people shooting and killing a lot of different types of people. Rivals. Strangers. Spouses. Boy- and girlfriends. Sometimes parents, even.
You see something here that you don't read about all that often. Someone killing his brother after an argument.
It's a story as old as Cain and Abel, of course. But nonetheless not something you see every day.
Of course, the punishments are different. Cain gets marked and cursed by the Lord. Here, Harold Cornelius gets 40 years in prison.
