The spate of shootings in Chicago over the past few days that left three people dead also injured several others, including the son of a Chicago police officer who was shot and killed three years ago.
Michael Bailey Jr., 30, was in a car on Tuesday afternoon on the city's South Side when someone in another vehicle shot him. The man's mother says Bailey doesn't know who shot him.
Bailey's father, Michael Bailey, was off duty after working as one of then-Mayor Richard Daley's guards when he was shot and killed in front of his home as he polished his car in July 2010. A man has been charged with murder and is awaiting trial.
Police said 20 people were wounded -- including two 16-year-olds -- in shootings across the city beginning Tuesday afternoon into Wednesday. About a dozen were shot in 12 hours, police said.
After midnight, the first murder of May happened in the South Shore neighborhood where a 27-year-old man was shot in the chest near his home at 68th and Cornell. Neighbors said the man was a father of three.
NBC News reports a 10-year-old boy was among the victims hurt in shootings. He was wounded in the right buttock and is believed to be in stable condition, police said.
The recent violence occurred as the Chicago Police Department released data that showed a 42 percent drop in homicides for the first quarter of the year compared to the same a year ago. The period of January 1 through April 30 will be the first time the department recorded fewer than 100 murders in the first four months of the year since 1963, officials said.
