Two boys were killed and two other teens were wounded in a shooting outside Benito Juarez High School on the West Side Friday afternoon. The shooting happened around 2:30 p.m. in the 2100 block of South Laflin Street, just as classes were dismissed for the day, officials said. One boy was dead on arrival at Stroger Hospital and another boy died after being brought there in “traumatic arrest,” officials said. Two other teens — a boy and a girl — were in less serious condition at the hospital, officials said. The boys were believed to be 16 years old and the girl 15. Police were told a suspect in a black mask, black hoodie and black North Face jacket was seen running west on Cermak Road and north of Ashland Avenue. A sophomore who only gave his last name, Nava, said he had been waiting in front of the school for his dad to pick him up when he heard shots down the block toward Ashland. “It was crazy,” Nava said outside the crime scene Friday evening. “I heard two shots and then everyone started running and went inside.” The 15-year-old went back inside and called his dad, who wasn’t far away. His 46-year-old father said he rushed through traffic to reach his son. “I was so nervous, I ran through the lights. I didn’t care,” he said. Read the full story through the link in our bio.
