South Carolina law enforcement officials said a teenage love triangle led to this summer’s fatal shooting of one of the girls’ boyfriends.

Authorities identified the victim as 16-year-old Trey Dean Wright of Johnsonville and said he was shot multiple times and found on June 24 on First Neck Road, about 45 miles west of Myrtle Beach. Florence County sheriff’s deputies said Wright was pronounced dead at the scene.

Officers arrested 19-year-old Devan Scott Raper of Conway one day after the shooting. The Florence County Sheriff’s Office said Raper allegedly shot Wright during an argument after the two had stopped on First Neck Road.

Authorities said the argument was “over a girl,” and at least one teen present during the incident allegedly took a video of the shooting.

Florence County sheriff’s deputies said the victim’s girlfriend, 17-year-old Gianna Kistenmacher of Myrtle Beach, is among those being charged with crimes related to his death.

The sheriff’s office said she was an accessory before the fact, claiming Kistenmacher brought Raper to where he met Wright while knowing Raper was armed and could have potentially hurt or killed the victim.

“They were complicit in bringing the armed co-defendant, Raper, to the incident location and knowing that there would be a confrontation,” Florence County Sheriff’s Office Maj. Michael Nunn told WBTW-TV. “They knew that Raper had presented a firearm to the victim and made threats to shoot him, according to the arrest warrants.”

All five original suspects were charged as adults under state law, authorities said.

Authorities in the weeks since the shooting have broadened their investigation, arresting nine total teens on charges related to the shooting.

Prosecutors have filed murder charges against three more Myrtle Beach-area teenagers: 18-year-old Hunter Kendall and 18-year-old Corrine Belviso, and 17-year-old Sydney Kearns.

Nine total teens have now been charged in connection with the June shooting of Wright. Some face murder charges, while others are accused of lesser roles, such as helping lure Wright to the site of the shooting and not attempting to prevent the fatal shooting.

“The hand of one being the hand of all is part of South Carolina law as well, so that’s the basis of the charge for each of those individuals,” Nunn told the TV station.

Ashley Lindsey, the mother of victim Trey Wright, said it’s been an emotional and trying few weeks for her as she’s dealing with the legal process following her son’s death.

“All this court hearing and bond court and stuff is driving me crazy,” she told Fox News Digital. “I don’t even have time to sit down and think half the time, on top of losing my precious baby.”

A GoFundMe page created following Wright’s death included a smiling, undated photo of him, one hand on his hip and a snake draped over his shoulders.

Sheriff on suspect’s motives

Florence County Sheriff T.J. Joye told reporters after the June 24 shooting that the entire incident “doesn’t make any sense.”

“It just didn’t need to happen,” he said. “We have a 16-year-old and a 19-year-old, both from our county, who decided to go out there and meet each other.”

Joye said the two “had issues with each other, and it was over a female.” Joye said.

“You got a 16-year-old who lost his life. You’ve got a 19-year-old who is going to be in jail the rest of his life. Over what?”

Raper has remained in custody without bond this week and is facing charges of murder and possession of a weapon during the commission of a violent crime. Kendall is also being held without bond.

Belviso and Kearns were granted $20,000 surety bonds and released this week while they await trial.

Prosecutors said they were unable to comment in detail on the case, citing the ongoing investigation, but said each of the nine suspects has been charged with felonies.

Crime had an element of premeditation

In addition to the number of suspects, this case stands out in part because of the number of teenagers who are believed to have known in advance about the confrontation and helped make it happen.

Authorities also say several suspects may have helped lure Wright to the scene where he was shot multiple times, despite knowing of the threats Raper made and knowing he had a gun.

Prosecutors plan to use both South Carolina’s “hand of one, hand of all” law, which in this case would apply to accomplices who may not have pulled the trigger but were accused of being present and not attempting to stop the shooting.

Evidence prosecutors have so far pointed to in this case includes arrest warrants, witness statements, and a video of the incident taken by a teen present during the shooting, according to court documents.
