A 16-year-old South Dakota boy killed his friend with a shotgun after the pair argued over a paintball game and playfully wrestled at the boy's home.
The victim, Dalton Williams was found lying in the entryway of the shooter's house around 5:30 p.m. Tuesday with a gunshot wound to the chest.
Paramedics rushed the high school sophomore to a nearby hospital, to no avail.
The accused shooter was arrested for first-degree murder at the scene and was being held in Hughes County, Pierre Police Chief Bob Grandpre said.
The teen is being charged as an adult, though he has not yet been arraigned or indicted, and officials are withholding his name because he is a minor.
The boys, both 16, were classmates at Riggs High School.
A 16-year-old witness who was hanging out with the boys said Williams and the other boy began to wrestle around jokingly after arguing about paintball.
The accused shooter then retrieved a semi-automatic shotgun, walked into the kitchen area and pointed it at the witness, according to an arrest affidavit.
The witness said he heard the gun click, then saw the accused shooter take a shotgun shell from a drawer, load the gun and point it at him again.
The witness said he then heard another click.
The witness told police he was trying to leave the house through a sliding glass door when Williams stepped in between him and the accused shooter.
The witness told detectives that the gun fired.
After observing a splatter, the witness left the house and called 911 in what is yet another disturbing incident involving gun violence and America's youth.
