CHICAGO (AP)  Chicago police are investigating shootings around the city that left seven people dead and several more wounded within a matter of hours. Police spokesman Hector Alfaro said the first shooting happened at about 6 p.m. Thursday and that the attacks continued into the early hours of Friday in various neighborhoods. Alfaro said police believe the shootings that left five men and one woman dead are unrelated. He said no arrests had been made as of early Friday. At least two of the victims died in drive-by shootings, including 18-year-old DeAndre Morgan who was killed as he pushed his son down the street in a stroller. Two others were shot and wounded when someone in a pickup opened fire on a basketball game on the city's South Side. Copyright 2010 The Associated Press. All rights reserved.
