Chicago police said the shooting occurred about 9:10 p.m. in the 6300-block of South Bell Avenue, and it left the officers in serious-to-critical condition.
They were taken to University of Chicago Medical Center, where a crowd of officers gathered after 10 p.m. Some officers could be seen hugging each other; others appeared emotional.
A female officer succumbed to her injuries, police said.
A male officer continues fighting for his life early Sunday morning.
Police said during a press conference early Sunday that the officers conducted a traffic stop on South Bell, during which shots were fired.
This marks the 27th time a Chicago police officer has been shot at this year and the 11th time an officer has actually been shot.

“Be careful, they’re still looking for someone,” a woman warned a neighbor as she walked by.

A 29-year-old female officer assigned to the Community Safety Team was shot and killed in the line of duty Saturday night. A second officer was also shot and is in critical condition.
“These officers put the safety and lives of others above their own, serving with courage and honor despite knowing the cost.
“Please pray for the family and loved ones of the fallen officer who will now face a world without her. Please also pray for the recovery of the officer who is fighting for his life.
“I ask you to please hold their fellow officers in your thoughts as they process this heartbreaking tragedy.
“We will never forget the sacrifices these officers made to protect this city. We cannot forget.”
