Woman shoots her brother while posing for facebook pics with weapons after drinking all night. Oh and for bonus points, she's underaged. Link here
It probably doesn't actually qualify for the Darwin Award because the death wasn't actually self inflicted. Close enough for me. He's still dead as a result of a stupid act. Story notes she may face manslaughter charges it turns out she was drunk.
The story doesn't mention many details (as usual). What kind of gun was involved? What steps were taken (if any) to ensure the gun was unloaded. What poses involved pointing a gun at her brother's head and pulling the trigger?
Cooper's four rules of gun handling:
1. All guns are always loaded
2. Never point a gun at anything you do not want to destroy.
3. Keep your finger off the trigger until the sights are on the target.
4. Be sure of your target and what is beyond.
All four rules have to be broken before someone may be hurt by an accidental discharge. Any one rule will break the chain.
