The period was more violent than the entire previous weekend _ when one person was killed and 14 wounded — and ranged across the city.
The burst of violence included three shootings in the area of 63rd Street and Sacramento Avenue within two hours that left a man dead and three others wounded, including two 16-year-old boys. Five miles away, in the Gresham neighborhood, four people were shot in three incidents.
The number of shootings and homicides in the city is more than double what it was the same time last year as Chicago experiences its most violent start of a year since the late 1990s. More than 500 people have been shot since the first of the year, and more than 100 of them have been killed.
One of the last shootings during the 20-hour stretch killed a 21-year-old woman in West Town. She was a passenger in a car when someone walked up and fired shots around 12:10 a.m. Wednesday, hitting her in the back.
