Pinien Dalmacy was 16 when he left Oak Ridge High School on the afternoon of October 9, 2025, and walked with classmates to the basketball courts at Vogt-Meloon Park off West Oak Ridge Road. Investigators say an earlier hallway confrontation began when 15-year-old classmate Jacori Redding bumped into Dalmacy and demanded an apology; the disagreement was set to be settled after school.

Deputies arrived at the park about 2:45 p.m. and found Pinien with two gunshot wounds; he did not survive. Sheriff John Mina described a brief chain of decisions that turned a hallway collision into a fatal shooting. Deputies say the accused shooter ran back to campus after the gunfire, was detained in the school cafeteria shortly after, and a firearm was recovered. By the next day arrests and charges were announced: manslaughter with a firearm and possession of a firearm on school property.

Friends and family publicly mourned. An online memorial asked the community to light candles in his memory, and a fundraiser remembered a smile that lit up every room. If anyone has information about what happened that afternoon at Vogt-Meloon Park, please share it with investigators.
