Heard that on the news this morning... it warmed the cockles of my heart!
Over in the east valley, we had a fatal shooting 18 months ago when some punks tried to crash a keg party. The crashers tried to walk off with beer, homeowner was knocked to the ground, punk kid drew a gun from his waistband. Homeowner - still on the ground, I believe - drew his own and fired. Chandler cops ruled it a good shoot.
Booze parties and kids have never been a great idea, but cell phones and social media means the word gets out to the world at lightning speed. Uninvited 'guests' always spell trouble.
