ELI5: How do forensic pathologists know which wound was the one that killed the person? How do they know that certain wounds were done posthumously?

They can tell which wound killed someone because it's going to be the one that damaged the most vital organs. So if you got shot three times and one was in the leg, one in the liver, and one in the heart, then they could all have been fatal, but the one in the heart will be the one killed you.    
    
They can tell if the wound was post-mortem because it won't bleed or bruise.
