prison social worker carlos peniera says they face a grim future. >> what kind of options do kids thisnal have? is it either the gangs or head north? >> the sad reality is the day they age out and step out of the door of the facility, they are going to find the same situation that put them here in the first place. >> they threw a grenade in here. >> and inside is just as dangerous. a few weeks ago, five kids were killed here in a gang clash. in a town square not far from her home, alex and axle's mother, dora agreed to meet me. even here, she was wary of being overheard talking about the gangs and her sons. >> i have to be very cautious to say what i am about to say. there are some things you are not supposed to say here. you join or you are killed. boys as young as 12, 15 years old had to leave. leaving seems to be the only solution. >> axle is in the u.s. now, but he may have to come home. he may be deported. what's going to happen to him if he has to come home? >> if he ended up back here and he didn't go back to the states quickly, they would kill him. >> that's what would happen.
