you don't know how a parent will retact to the killer of the child or what they will want to know or not know about the last moment's of their child's life. what happened to them? it's an awful thing to know. yet, kerry had to know. watch what happens outside the san diego jail. >> i think if you're a parent you want to know what happened. you want to know how they took your child. if a lesson can be learned from amber, then i want it out there. >> and so early in may she tried to schedule a visit, was told none was available. so kerry had a bold idea. why not ask the mother to give up one of her visits with her son? so one afternoon she waited outside the jail as gardner's mother approached. it didn't go well. i just want to visit your son. >> excuse me. >> don't touch me, i'll hit you. i'm not. stay away from her. i'm not here to harass you. i want to talk to your son.
