Gwinnett County police Cpl. Edwin Ritter tells the Gwinnett Daily Post the teen threatened to kill his family with the machete before the relatives locked themselves in a room at their home in Buford.
Police say they were called to the home on Windward Gate Lane around 3:30 p.m. Monday and were immediately confronted by the 15-year-old.
The officers and other witnesses told investigators the teenager exited the house and charged the officers.
Ritter said that despite commands to drop the machete, the boy refused to comply and was shot. His name was being withheld until next of kin were notified.
