Seventeen-year-old Carter J. Conklin, a senior at Millville High School who participated in the school chorus, was found dead in his Engle Road home in Millville, Pennsylvania, on September 18, 2025. The Columbia County Coroner ruled his death a homicide after determining he had suffered a single gunshot wound to the head. The state police opened the investigation.

Investigators quickly focused on someone who lived in the same household. Arrest records state that 16-year-old Adam Bartosic, the son of the mother’s live-in boyfriend and a fellow student at Millville Area High School, was charged with criminal homicide and taken into custody; he turned 17 the day after charges were filed. Court documents say the affidavit alleges planning by the suspect, including searches related to killing on his phone, and that Carter’s mother had reported recent aggressive behavior and threats from Bartosic toward her family. A neighbor reported hearing what they believed were gunshots at about 12:30 a.m. the morning of the death, and a preliminary hearing was set for the end of September.

Did anyone in Millville see or hear anything unusual on Engle Road around that night, or have information about tensions in the household beforehand?
