Shooter is 'rarely at home' and works long hours but is 'friendly', neighbors say

Two brothers, 16 and 15, and their friend, 16, died in the incident at 4am Monday 

As of Wednesday morning the homeowner had not been charged with any crime

But he has been left 'crushed' by the deaths outside his house in Conyers 

Police said the boys, all wearing masks, tried to rob three people in the yard 

One of the teenage intruders is said to have brandished a handgun and fired shots at the inhabitants of the home before a man returned fire

Rockdale County Sheriff said the incident could be a 'stand your ground' case
