Leadership by example huh? All people present are all to blame. 

None of the stories match and conveniently the females "left". 

The Mother of the Year Award clearly goes to the Clark's mother.  

Doreen, SHOULD BE FIRED! Is this how community leaders act? Was she respecting the health of her husband or son when she left them to fight it out? She KNEW there was a gun, ammo, alcohol and fighting between at least one person who was drunk for sure. She SHOULD have called LEO. But she left. Chances are HIGH, this family has a history of drinking and violence between these two so the Mom and girlfriend left for them to "work it out".  

The autopsy will determine if the victim was drinking which will at least be able to prove or disprove the shooter's story. 

Domestic violence is NOT ok. Arguments, alcohol, guns are present, there is only one ending. Doreen enabled this ending by not calling.

The gun should have been secured. Fire her. Charge her as an accessory. Blood is on her hands.
