IN a U.S. city troubled by allegations of police misuse of force, a Chicago police officer shot and killed a male college student and a mother of five, both black, early Saturday morning, and police shot another person at a separate location hours later.

    The police department of the nation’s third-largest city is under a federal civil rights investigation for its use of deadly force and officer discipline.

    A recently released video of the shooting death of a black teenager by a white officer in 2014 has sparked protests, with activists calling for Mayor Rahm Emanuel’s resignation.

    The morning’s shooting happened in the West Garfield Park neighborhood on the city’s west side.

    “Upon arrival, officers were confronted by a combative subject resulting in the discharging of the officer’s weapon, fatally wounding two individuals,” police said in a statement.

    The Cook County Medical Examiner’s office identified the dead as Bettie Jones, 55, and Quintonio Legrier, 19.

    Family members of Jones said that Legrier, a sophomore at Northern Illinois University, was home for Christmas and visiting his father, landlord of the two-story wooden frame building where the shooting occurred.

    Family members said police were called after Legrier threatened his father with a metal baseball bat. (SD-Agencies)
