Britney Brinson was inside her Allen Road home on Hilton Head Island shortly before 5 p.m. Saturday when she heard gunshots ring out and a car peel off.

She looked outside where her 8-year-old second cousin Khalil Singleton, a student at Hilton Head Island Elementary School, was playing and saw him fall to the ground.

Brinson, a nurse at Beaufort Memorial Hospital, ran out to the boy and began performing CPR. Beaufort County Sheriff's deputies and Town of Hilton Head Fire & Rescue Division paramedics arrived moments later and rushed Khalil to Hilton Head Hospital, where he was pronounced dead.

The Beaufort County Sheriff's Office said on Saturday that Khalil was caught in the crossfire of a gun battle, and deputies arrested four men for questioning in connection with his death. Khalil was shot on the left side of his torso during the exchange of gunfire, according to an incident report.

Brinson said one of the men who the Sheriff's Office says is involved in the gunfight, Tyrone Robinson, saw the wounded boy and kept walking.

Robinson, who also lives on Allen Road, was allegedly involved in a feud with Aaron Young Jr., 19 and his father, Aaron Young Sr., 36, that had nearly become violent on one previous occasion, according to a news release from the Sheriff's Office early Sunday.

Both of the Youngs have been arrested, and each has been charged with one count of discharging a firearm into a vehicle after allegedly shooting at Robinson's unoccupied car, which was parked on Allen Road. Both men are being held on $150,000 bond, according to the Beaufort County Detention Center jail log.

Robinson also was arrested on unrelated burglary charges and has been charged with pointing a firearm at a person, with bond set at $75,000. The firearm charge stemmed from an earlier incident on Wild Horse Road, during which Robin allegedly brandished a handgun during a fight with Aaron Young Sr. The weapon went off in the struggle but no one was injured, the Sheriff's Office said.

A fourth man, 35-year-old Jontu Singleton, also was questioned about the shooting that killed Khalil and was arrested on unrelated burglary charges. Singleton is being held on $25,000 bond, according to the jail log.

Brinson said that the day of the shooting, Khalil had been playing with Singleton's son. Her 4-year-old son also was a frequent playmate of Khalil's, and the boys called each other best friends.

"(Khalil) was a child who loved life," Brinson said. "He didn't deserve this."
