A 13-year-old is in custody at the Alvin S. Glenn Detention Center for allegedly stabbing and killing her 18-year-old brother, Columbia police say.
Columbia police responded to a call around 9:30 a.m. Sunday for a reported assault. They found the 18-year-old inside a home on the 1900 block of Willow Street with a life-threatening stab wound to his upper body.
