A teenage boy was shot and killed Tuesday night in a Woodlawn neighborhood alley.The 15-year-old was standing in an alley just before 8:30 p.m. in the 6600 block of South Champlain Avenue when someone opened fire, striking the boy in the abdomen and left leg, Chicago police said.Officers responded to a call of shots fired and an anonymous 911 caller who said they saw two males running north and heard a someone scream: "My son got shot!" according to a police report.The boy, of the city's Auburn Gresham neighborhood, was found lying on the ground, next to a red book bag and a damaged black phone.He suffered more than a dozen gunshot wounds and was taken to Comer Children’s Hospital, where he was pronounced dead at 8:51 p.m., police said.Community activist Andrew Holmes was working to get in contact with the boy's family Wednesday afternoon to help provide them with counseling and therapy."I know they're hurting," Holmes said. "You watch him go out that door, you say, 'I love you,' but that door will never open for him to come back in."Holmes told the Chicago Sun-Times he was "terribly disturbed" by the fatal shooting."The world hasn't had a chance to experience what his future could've been, and that's not only for that 15-year-old but for every teenager that is shot and killed," Holmes said. "I feel for his mother and father. ... That's a lot of pain, that's a lot of pressure on your heart."Area 1 detectives are investigating but no one was arrested.
