Robert Stewart, 45, allegedly shot and killed seven patients and a nurse at a nursing home in Carthage, North Carolina yesterday until police shot and wounded him. Three other people, including a police officer and a nursing home visitor were wounded in the attack. A witness said Stewart was armed with a rifle, shotgun and other weapons. Stewart's possible motives are unclear, as he was not employed by the nursing home, nor did he know any of the patients. He's facing eight counts of first-degree murder, plus felony assault on a police officer. Other charges are pending.
