CHICAGO — Chicago police today are investigating shootings around the city that left seven people dead and several more wounded in a matter of hours.

Police spokesman Officer Hector Alfaro says the first shooting happened about 6 p.m. Thursday and that the attacks continued into the early hours of today in various neighborhoods.

Alfaro says police believe the shootings that left five men and one woman dead are unrelated. He says no arrests had been made as of early today.

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 truck opened fire on a basketball game on the city's South Side.
