Jesse Rainey and seven of his friends were spending the weekend in an empty house that belonged to the grandmother of one of the teenagers when a few of them decided to play a prank on their friends by faking a home intrusion, ABCNews.com reported.
"One of the young men cut the lights to the house, then a few of the other guys snuck back inside, wanting their friends to believe there was an intruder," Colbert County Sheriff Ronnie May said.
One boy targeted by the prank became scared and fired a shot into Rainey's head with a .38 caliber handgun, May said.
"This was a prank that went terribly wrong," he said.
May said the shooting has been labeled "accidental" and that after interviewing all of the boys and conferring with the district attorney's office, no charges will be filed. Drugs and alcohol were not a factor in the shooting, authorities said.
