Mourning families accuse officers of excessive force

The families of two black Chicagoans killed by police accused officers on Sunday of having used excessive force and Mayor Rahm Emanuel of having failed them, piling pressure on a city facing a US federal probe over possible racial bias in policing.

Police 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, said her cousin Evelyn Glover.
