When Hadiya Pendleton was shot in a Chicago park, she quickly became a symbol of the deadly street violence in the city. But nearly every day, someone is gunned down in Chicago, often the result of gangs fighting over territory to sell drugs.
This past fall, "48 Hours" correspondent Maureen Maher and CBS News correspondent Armen Keteyian began reaching out to some of the victims who are hurting and some of the people who are fighting back in this city at war over guns, gangs, and drugs.
"I wish you guys could've been here asking me about, you know, the dancing at the inauguration, but unfortunately this is what we're dealing with," Hadiya's father, Anthony Pendleton, told Maher.
"We know from years of working the streets ... that much of the gang-related shootings -- are drug related," Jack Riley, who heads up the Chicago division of the Drug Enforcement Administration, told Keteyian.
To get the gangs, Riley and the DEA go after their drugs -- heroin in particular.
"That's why I look the way I look, that's why I don't sleep a lot," he said. "One homicide in this city is too many. One person abusing heroin in the suburbs is too many."
Paula Nixon started using heroin when she 16. "... and the first time I did it ... I was in my family room ... and I was thinking, 'this is the best feeling in the world,'" she said.
Heroin has taken many of Paula's friends, but she can't kick it on her own.
"I'm not strong enough... if I saw heroin in front of me right now I can't tell you that I wouldn't do it," she said. "There is no amount of willpower I have on my own that I can stop."
With drug dealers at his doorstep, David Muhammad risked his life to stop them.
"Every day for about a year I videotaped them," he said. "It's worth it to lose my life if I have to try to slow this down."
Over the past six months we've watched David Muhammad stand up to drug dealers, Paula Nixon battle her heroin addiction and the Pendletons search for justice.
The Chicago Police force and the DEA have been hunting down drug-dealing gangs and "48 Hours" is there as it all unfolds.
