Not just uncaught murderers, there are a lot of people who have killed without legally being considered murderers.
People who killed people in accidents such as driving accidents or hunting accidents
People who killed in self defense
Soldiers who killed enemy soldiers
Executioners
Police officers who have killed on duty
Doctors and nurses who have made mistakes that accidentally killed patients


I know two that I can verify. One is a combat vet who had to kill during a fire fight in Iraq. The other is an outlaw biker who I went to school with, he shot a rival club member and a few years later got caught on a trafficking charge and somehow the police were able to connect him to the murder after his arrest. He’s obviously in prison now. It’s weird to know that after he committed the murder we reconnected and hung out a few times, there I was sitting at a bar laughing and joking with a killer without even knowing it.
