In a tragic incident in North Carolina, a 16-year-old student, who reportedly brought a knife to school, was fatally injured during an altercation with another student, whom authorities describe as his friend. The incident took place at North Forsyth High School in Winston-Salem, officials reported on Thursday.

District Attorney Jim O’Neill labeled the event as “senseless” and referred to the fatal stabbing as an “accident,” according to a report by WXII.

The confrontation occurred on Tuesday morning and was recorded on video. Officials have urged the public to refrain from sharing or engaging with these videos out of consideration for those affected, as noted in a CrimeOnline report.

These videos, along with eyewitness accounts, have been integral to the investigation, O’Neill stated.

The victim, identified as Cameron Graham, had the knife in his possession at school. An 18-year-old student reportedly attempted to disarm him during the struggle, which resulted in Graham being stabbed in the chest. O’Neill explained that both students were grappling with the knife when it inadvertently struck Graham, causing a fatal injury to his heart.

O’Neill emphasized, “This was not an intentional act by the 18-year-old. The evidence does not indicate any intent beyond an unfortunate accident.” He concluded that there is no legal basis to charge the 18-year-old involved.

The 18-year-old has not been identified, but O’Neill said the two students were friends and had ridden the bus to school together and talked earlier Tuesday morning.

Graham’s family said they were “seeking legal counsel to assist with this investigation,” apparently disagreeing with officials’ determination the stabbing was accidental and attributing that decision to “Sheriff Kimbrough and the police department” and not the district attorney.

“We have lost two family members tragically, one shot ten times in the back, and now a fatal stabbing, and have received no justice,” Graham’s aunt, Charlita Summers, said. “We are asking that any legal entities that are willing to help look further into these investigations will come forward to help the family at this time.”

It’s not clear what shooting Summers referred to.

For his part, Forsyth County Sheriff Bobby Kimbrough Jr. said that metal detectors weren’t in use the day Graham brought his knife to school.

Kimbrough, Winston-Salem Police Chief William Penn Jr., and Winston-Salem Forsyth County Schools Superintendent Don Phipps all said that school safety was a top priority and that metal detectors weren’t the sole answer.
