Police say statements from the survivors indicate that 47-year-old Sandra Lyn Palmer shot and killed 14-year-old Maurice Edmonds II and wounded her daughter and boyfriend before shooting and killing herself Monday.
Palmer's daughter, 18-year-old Danielle Jameison, and Palmer's boyfriend and Edmonds' father, 46-year-old Maurice Eugene Edmonds, were wounded. Police chief Ken Miller said Edmonds and Jameison had improved to stable condition and their stories confirmed the forensic evidence.
Police say the family was involved in a dispute early Monday, though investigators did not say what sparked the dispute. Police say Palmer left the room and returned with a gun.
Autopsies results were not immediately available.
Jameison is a sophomore at UNC Chapel Hill.
