Naima Liggon, of Waldorf, Maryland, died in the early Sunday violence, at Metropolitan Police in the nation's capital. Police said the stabbing unfolded outside a McDonald's in the 1900 block of 14th Street, Northwest. Liggon was transported to a hospital in a private vehicle, police said. Officers responded to the hospital just after 2 a.m. on a report of a teen girl with stab wounds, and despite life-saving efforts, she died. Later Sunday, police said a 16-year-old girl, also of Waldorf, was arrested, and found in possession of a knife. She has been charged with second-degree murder while armed, assault with intent to kill, aggravated assault, felony assault, and carrying a dangerous weapon. The teen appeared at a hearing Monday in D.C. Superior Court and Detective Brendan Jasper testified that Liggon was stabbed in an argument over “sweet-and-sour sauce” among three girls outside the McDonald’s just after 2 a.m.
