The families of two black Chicagoans killed by police have accused officers of using excessive force, piling pressure on a city facing a US federal probe over possible racial bias in policing.
Police, responding to a domestic disturbance call, shot Quintonio LeGrier, 19, a male college student who was visiting his father, and Bettie Jones, a 55-year-old mother of five, on Saturday.
Family members said police were called after LeGrier threatened his father with a metal baseball bat. Jones, who lived in a first-floor apartment, was shot through the door, according to her cousin, Evelyn Glover.
Police said LeGrier was being combative. They said Jones was killed by accident and extended their condolences.
"This needs to stop. No mother should have to bury her child," Janet Cooksey, LeGrier's mother, told a news conference.
She said her son was shot seven times. She previously told reporters her son had been suffering from mental illness.
High-profile killings of black men by US police officers since mid-2014 have triggered waves of protest - including in Chicago, the country's third-largest city - and fuelled a civil rights movement under the name Black Lives Matter.
A Chicago police video of the fatal shooting of another black teenager sparked protests last month, with activists demanding the resignation of Mayor Rahm Emanuel, a former chief of staff to President Barack Obama.
A federal investigation is under way over the department's use of deadly force and officer discipline.
