Three dead and at least 18 wounded over weekend in Chicago; 15-year-old stabbed downtown

As Chicago prepares, sort-of, for the Democratic National Convention in August, the shootings of course continue in the city. 

Over this past weekend, three people were shot to death and at least 18 others were wounded. 

Regarding the homicides, a man driving was shot dead in Woodlawn on the South Side. 

On early Saturday, a man having an argument was fatally shot in Park Manor at a Maxwell Street Polish. Around that same time, a man was shot to death in Chicago Lawn.

There was at least one stabbing, Sunday was a clear and beautiful day, which makes the afternoon stabbing of a 15-year-old boy who was stabbed, fortunately not fatally, in Chicago's Loop.

Until about five years ago, violence downtown was rare.
