A South Carolina man has been sentenced to life imprisonment for the tragic murder of an 8-year-old boy who was on vacation in the state.

Charles Montgomery Allen, aged 40, admitted guilt on Thursday to one count of murder and five counts of attempted murder, as stated in Florence County court records obtained by Law&Crime.

General Sessions Court Judge Steven DeBerry IV handed Allen a life sentence for the fatal shooting of young Quarius Dunham. Additionally, Allen received 30-year sentences for each of the attempted murder charges.

The tragic event happened on May 28, 2022, along Long Old River Road in Florence County, approximately 90 miles east of Columbia.

On that day, Allen was reportedly at his residence, indiscriminately firing a rifle and a shotgun at passing vehicles, as per law enforcement accounts.

“There was no motive. Likely under the influence of meth. He has a history,” Florence County Sheriff TJ Joye explained to CBS affiliate WBTW at the time. “He’s now detained without further incident. It’s a senseless, senseless act.”

At the time, Quarius was visiting from out of state with his family, who hail from Portsmouth, New Hampshire.

The little boy was riding with his family in a car that passed by Allen’s house when he was shot and killed. A woman in the same car was also shot but survived, law enforcement told WBTW.

The fatal bullet struck Quarius in the neck. He was rushed to a nearby hospital but was later taken off life support.

Allen fired at two other vehicles, authorities said. The child’s father was driving one of those vehicles and was also shot but survived.

Quarius was a third grade student at Little Harbour School when he died. The school district issued a statement after the shooting.

“It is with the heaviest of hearts that I share the sad news that one of our third grade students at LHS was killed this weekend,” Portsmouth Superintendent of Schools Steve Zadravec said. “His family was on vacation and were victims of a random shooting in South Carolina. An event like this touches our community as a whole. Our hearts are with the family as we support each other through this unbelievable tragedy.”

SWAT team members arrested Allen after he returned home. He was found with a large cache of weapons, authorities said.

“It’s sad. It’s heartbreaking,” the sheriff added. “We’ve got an 8-year-old shot for no reason. No reason.”

The defendant was originally also charged with several other crimes, including possession of a weapon during the commission of a violent crime and multiple counts of discharging a firearm into a vehicle. Those lesser charges were dropped this week, court records show.

During his sentencing hearing, the condemned man’s attorney said his client accepted what he had done and, upon learning about the child’s death, hung his head in shame, according to a courtroom report by Florence-based ABC/CW affiliate WPDE.

Allen, for his part, also apologized.

A relative of the defendant also spoke up to directly address the victim’s family and said, “The only thing I can offer are my prayers.”
