Maddison Olivia Leightenheimer, 22, died on April 24, 2026, after being struck by a bullet inside an apartment at the Cross Yard at Plantations at Haywood in Greenville. Police responded about 5:50 p.m. that Friday after a firearm was discharged in the unit. She was taken to Prisma Health Greenville Memorial Hospital, underwent surgery, and died later that night.

Greenville police treated the incident as a criminal investigation. A warrant reported by local media identified 24-year-old Seth Porter as Maddison’s boyfriend and said she was in another room when the bullet struck her. Porter was arrested and charged with manslaughter; no other suspects have been publicly identified. The coroner and police said the manner of death remained under investigation as authorities reviewed how the weapon was handled and whether the shooting was reckless.

Born July 10, 2003, in Portsmouth, Ohio, Maddison, who also went by Olivia, graduated from Clay High School in 2021 and had ties to Portsmouth Baptist Church. She was employed as a pharmacy technician at Prisma Health Greenville Memorial Hospital and had recently received a promotion. Did anyone who knew Maddison or was in that apartment that evening see anything that could help clarify what happened?
