 Prince George's County police say the little boy from Washington, D.C. died of his injuries at a hospital Saturday night. Police say the other two were adults. One, a woman, was grazed by a bullet. The other, a man, had non-life-threatening injuries. Anyone who went to the party or has information on the shooting is being asked to contact the department's homicide unit. There's also an option if callers want to remain anonymous. A reward up to $25,000 is being offered for information that leads to an arrest and indictment in the case. Shana Stulen, WTOP News.
