One person was killed and eight others wounded in a pair of shootings late Friday night in downtown Chicago's the Loop district, just hours after Chicago lit the city's official Christmas tree just blocks away in Millennium Park. Seven teens were injured in the first shooting, which police said happened near the intersection of State and Randolph streets near the Chicago Theatre at around 9:50 p.m. local time. Two people were shot, one fatally, during the second shooting near Adams and Dearborn
