>> i got some recording this number is not in service. i said, this is a prank. >> this is the closest thing to an address he said he had for a singer he said was cheryl johnson. the fbi looked hard and could never find her. >> it says to me that cheryl johnson didn't exist and he made it up. >> williams says only after that call from a gas station did he turn around to cross back over the bridge again. police would stop him moments later. you said, i know this is about those boys, isn't it? >> correct. that's what i said. >> pretty damning statement, don't you think? >> no. i mean, the perception in atlanta was at the time kids were missing. and i think if i'm not mistaken, the perception was a lot of young males are missing. that's what i asked. this is about those kids or boys or something like that, isn't it? >> remember what fbi agent mike mccomas said he saw when he got to the scene?
