I think a few people are under the assumption that the father tried or intended to kill his daughter's assailant, while the articles suggest the complete opposite.
I don't know what the father tried to do, but I am going to assume he reacted paternally to get his daughter out of harm, and to punish the guy who would dare harm his little princess. The guy could have had a broken nose and been unconscious, causing him to suffocate from his own blood, or he could have had a shattered larynx, I don't know the specifics of the man's injuries. I just know they caused his death, and the father did not mean to cause death, he was probably just reacting.
I like how most threads dealing with death bring up the death penalty, lol.
