According to police, officers were dispatched to the Little Village neighborhood in the early hours of March 29 when the department's ShotSpotter technology detected eight gunshots. When police arrived, Adam and 21-year-old Ruben Roman fled, authorities said.
An officer shot Adam once in the chest after an "armed confrontation" in an alley, police said. Adam died at the scene.
Lightfoot and other city officials have offered various narratives around whether Adam had a gun or not. Earlier this month, Lightfoot suggested Adam was holding a gun, saying "an adult put a gun in a child’s hand." And on Saturday, prosecutors alleged Adam was holding a gun when the officer shot him.
But on Thursday, a Sarah Sinovic, chief spokeswoman for the Cook County State’s Attorney, said "an attorney who works in this office failed to fully inform himself before speaking in court. Errors like that cannot happen and this has been addressed with the individual involved. The video speaks for itself."
Also Thursday,Lightfoot's phrasing changed, and she said Adam was "a child who was in contact with an adult who had a gun." Asked whether Adam shot at an officer, she said: "I've seen no evidence whatsoever that Adam Toledo shot at the police."
The officer has been placed on administrative leave for 30 days.
A case incident report identified the officer who fired the shot as 10th district patrol officer Eric Stillman. Stilman, a 34-year-old white man, has been a Chicago police officer since August 2015, according to the report.
Stillman has no prior complaints filed against him and was a 2016 recipient of the Superintendent's Award of Valor, according to the Invisible Institute, which records police interactions with the public.
