The shooting happened about 4:32 p.m. on the 3100 block of West Peterson Avenue, police said.
Preliminary reports stated two teens, 15 and 16, were walking with a group when they encountered another group and began arguing. Someone in the second group pulled out a gun and fired, striking both of the victims, police said.
The 15-year-old, identified by the Cook County medical examiner's office as Sergio Torrez of the 6700 block of North Maplewood Avenue, suffered a wound to his upper back and was pronounced dead at 5 p.m. at Saint Francis Hospital in Evanston.
The second youth, 16, suffered a wound to his arm.
UPDATE: Des Plaines man charged with killing. A 19-year-old Des Plaines man was denied bail today after he was charged with killing one 15-year-old boy and wounding another one in a shooting that began when a North Side crowd ignored his flashing of a gang sign.
James Galambos, of the 900 block of Beau Drive, was charged with first-degree murder and aggravated battery with a firearm in the shooting that killed Sergio Torres of Chicago’s West Ridge neighborhood. The other victim, a 15-year-old Evanston boy, was shot under his right arm but survived.
On that afternoon, Galambos encountered a group of people that included Torres and the other victim. Galambos demanded to know what gang the group’s members belonged to and then flashed a gang sign, court documents state. When no one responded, Galambos pulled out a handgun and fired into the group, striking the two teens.
