Two people were killed on Chicago’s West Side after a police-involved shooting early Saturday morning. Family members say 57-year-old Bettie Jones, of the 4700 block of W. Erie, was killed. The Cook County Medical Examiner’s Office listed Jones’ age as 55. The man was identified as Quintonio Legrier, 19, also of the 4700 block of W. Erie.

Family members tell NBC 5 that Jones was a mother of five and Legrier was a Northern Illinois University student studying engineering. The two were shot about 4:25 a.m. in the 4700 block of West Erie as officers were responding to a call of a domestic disturbance, according to a statement from the Chicago Police Office of News Affairs.

Neighbors and family members at the scene said that the domestic disturbance stemmed from the 19-year-old threatening another man in the home with a metal baseball bat. They said the woman, who also lived in the building, opened the door for police and was shot shortly after.

According to the Chicago Sun-Times, Latesha Jones, the woman’s daughter, said she woke up when she heard three gunshots. She walked to the front door and saw her mother bleeding on the ground, she said. “She wasn’t saying anything,”

Jones said, who added that she could feel her mother breathing before she was taken away by paramedics. Jones, whose family has lived in the building for a year and a half, said that police shot her mother from outside the home after she opened the door, reports the Sun-Times. Jones’ family told NBC 5 they plan to file a lawsuit.

Shortly before 9:30 a.m., Chicago Police Chief of Detectives Eugene Roy said in a press conference that officers from the 11th District responded to a call of a domestic disturbance early Saturday morning.

“Upon their arrival, they were confronted by a combative individual, resulting in an officer firing shots, fatally wounding two individiuals,” Roy said. “The matter is under investigation by the Independent Police Review Authority and further questions regarding this matter should be directed to them,” he added.
