A 16-year-old boy in South Dakota was fatally shot on Tuesday by a friend after an argument over a game of paintball.

Dalton Williams was shot at his Pierre, S.D. home after he and Braiden McCahren argued over a paintball game and playfully wrestled.

Williams was rushed to the hospital with a gunshot wound to the chest which claimed his life.

The alleged shooter is being charged as an adult, according to an arrest affidavit. The 16-year-old gunman was charged at his home with first-degree murder, according to the Capitol Journal.

Pierre Police Chief Bob Grandpre stated that the accused gunman was taken on Wednesday to a jail in Hughes County.

"We're continuing the investigation to make sure we understand everything that we believe happened inside the house," Chief Grandpre said, according to Fox News.

While McCahren has been arrested, he has yet to be arraigned or indicted for the crime.

The Pierre police department also spoke with a third teen identified only as "T.Y." in court documents who said McCahren picked up a .22 caliber rifle from a gun shop while doing errands earlier that day.

The court documents state: "T.Y. advised that they had gone back to the residence and had unloaded some items from the vehicle and that Braiden had taken the .22 caliber rifle into the residence where he cleaned the gun."

"T.Y." allegedly saw McCahren loading the semi-automatic shotgun in the kitchen and Williams moved in front of the shooter. The 16-year-old witness told police that he saw Williams shot. "T.Y." then left the residence and called emergency services.

Law enforcement officials are working with the Pierre School District as well as mental health professionals to provide support to the community.

Williams was a sophomore at Riggs High School along with the accused shooter and the witness.
