The Chicago police officer who shot and killed a mother of five and a distraught teen wielding a baseball bat in the early hours after Christmas has now     been identified. A Reader analysis of internal police records and scanner audio from the day of the incident point to Robert Rialmo as the officer who     fatally shot Bettie Jones, 55, and Quintonio LeGrier, 19, on December 26.



    According to the scheduling logs obtained by the Reader, Rialmo was assigned to work an overnight shift in beat 1172R beginning at 10:30 PM on December 26.





             A dispatcher then asked, “What unit and where are you?”



             The family’s attorneys contend that the officer who shot Jones was standing far away from the door when he fired into the hallway, where LeGrier was also     struck by the officer’s bullets.



             “We got two down, two down,” Rialmo or his partner replied.
