CHICAGO : Police in Chicago shot and killed three people Saturday, including a mother of five who they said was shot “accidentally” when officers responded to a domestic disturbance.

A police statement said that on arriving in response early Saturday to the disturbance, “officers were confronted by a combative subject resulting in the discharging of the officer’s weapon, fatally wounding two individuals.”

The killings are the first in the city since protests last month over a video showing a white police officer in Chicago shooting 16 times at a fleeing black teen, who died at the scene. The shooting, which took place in 2014, has triggered a federal civil rights probe into the police. Local media identified the two African-American fatalities as Bettie Jones, a mother of five, and 19-year-old engineering student Quintonio LeGrier.
