CHARLOTTE, N.C. -- The 16-year-old accused of shooting and killing a fellow student at Butler High School in Matthews three weeks ago is charged with second-degree murder.

Previously reported:

Monday, a grand jury returned the indictment against Jatwan Cuffie.

Cuffie was initially charged as an adult with the first-degree murder of 16-year-old Bobby McKeithen.

An indictment has transferred the cast from District Court to Superior Court, which means his next court day its unknown.

Police accused Cuffie, a ninth-grader, in the October 29 shooting death of 16-year-old Bobby McKeithen, a 10th-grader at Butler High School, during a fight in a crowded hallway.

Last week, authorities charged three students after a post on social media suggested there was a gun on a high school campus, one of three instances in which weapons were reported at schools.

Several days later, Charlotte-Mecklenburg Schools announced it was increasing security measures, including random wanding of students and random searches of backpacks and bags.
