The shootings happened between Thursday afternoon and Friday morning.
All of the deceased victims were identified by the Cook County Medical Examiner's Office.
Among the dead is Kristle Jackson, 23, a woman described by her family as an innocent victim.
But Chicago Police Superintendent Jody Weis says most of those who were killed had documented gang ties and because of the code of silence, witnesses are not talking.
No suspects are in custody for any of the killings."She was joyful to everybody. And what they did to my daughter she didn't deserve it," said Brenda Jackson, victim's mother.
Dozens of Jackson's relatives gathered Friday night at the family's North Side apartment. Her cousin, Kimberly Jackson, says she was the last to speak to her.
"She told me she was going with her friend. And for her to tell me that, I didn't have to question it because she was always a smart girl," said Kimberly Jackson.
Her family says Jackson was shot around midnight at 59th and Wabash as she was leaving a restaurant. Two men were also shot but they survived.
Mayor Daley, a longtime advocate of gun control, was visibly upset when asked about the violence.
"Welcome to America. Americans kill each other. Every day. We kill each other. Not in Afghanistan. Not in Iraq. Good ol' America. We manufacture the guns and kill ourselves," said Daley.
"The people committing these acts of violence are members of the communities. They have family and friends who are fully aware of their activities," said Weis. "We are not Chi-raq. We are Chicago."
Police are asking witnesses to step forward. And residents are concerned.
"Kids that are 14, 15, they should be at home at a certain time. Parents are not involved in seeing what is going on. Innocent people are getting killed. So it's sad," said Elizabeth Mahlum.
As for Jackson's family, they want the gunman in custody.
"I just want the killer who done this to my sister," said Marceia Jackson, victim's sister.
Supt. Weis planned to be on the streets Friday night and will join Chicago officers in hot spots throughout the city. Next week, Weis said he will announce his 'summer crime initiatives,' a plan to deal with the violence as summer approaches.
