Chicago weekend shootings: 7 dead, including a family of four, 21 wounded, including a 3-year-boy shot in the head

Chilly temperatures arrived for the first time in months in Chicago. But that didn't lighten carnage.

Seven people were shot to death over the weekend, including a family for four shot Saturday while having dinner by a neighbor. The alleged shooter killed a fifth person in the same building, which is the Dunning neighborhood on the Northwest Side.

On the Southwest Side, a three-year-old boy is among the 21 who were wounded during the weekend. The toddler, who was sitting in a car, is in critical condition.
