Maddison Olivia Leightenheimer, a 22-year-old woman from Greenville, South Carolina, died on April 24, 2026, after a shooting inside an apartment at the Cross Yard at Plantations at Haywood apartment complex in Greenville. Police responded around 5:50 p.m. that Friday after a firearm was discharged inside one of the apartments. Maddison was struck at least once, and the wound was serious enough that she was rushed to Prisma Health Greenville Memorial Hospital, where she underwent surgery.
Despite those efforts, she died from her injuries later that night.
The case began as a frantic emergency inside a residential apartment, but it quickly became a criminal investigation. Authorities said the gun was fired inside the apartment and that Maddison was hit by the bullet. A warrant reported by local media said the man charged in the case, 24-year-old Seth Porter, was Maddison’s boyfriend and that she was in another room when the bullet struck her. That detail suggests investigators were looking closely at how the weapon was handled, where Porter was positioned when it fired, and whether the shooting was reckless rather than intentional.
Greenville police arrested Seth Porter and charged him with manslaughter. As of the available reports, he was the only person publicly identified as arrested or charged in connection with Maddison’s death. No additional suspects were named in the available online reports, and there were no reported trial or conviction updates available yet. The coroner’s office and Greenville Police Department said the manner of death remained under investigation, indicating that authorities were still reviewing the circumstances surrounding the fatal gunshot.
Maddison, who also went by Olivia in her obituary, was remembered as someone with ties beyond Greenville. She was born in Portsmouth, Ohio, on July 10, 2003, and was the daughter of Harold Joseph Leightenheimer and Trish RoyAnne Burke-Leach. She was a 2021 graduate of Clay High School and had attended Portsmouth Baptist Church while living in that area. At the time of her death, she was working as a pharmacy technician at Prisma Health Greenville Memorial Hospital, the same hospital where doctors later tried to save her life. Her obituary said she had recently received a promotion.
Her death left family and friends grieving a young woman whose life had moved from Ohio to South Carolina and was still unfolding. Online memorials described her loss as sudden and unexpected, while local news reports framed the case around the fatal apartment shooting and the manslaughter charge that followed. The public record available so far shows a fatal firearm incident inside a Greenville apartment, one arrest, and an open investigation into the precise circumstances that led to Maddison being struck by the bullet.
