fbi agent mike mccomas rushed to the scene. the driver was standing by the highway. >> he was talking with the officers. saw a black male. he had on a baseball hat. had on glasses. >> the young man was wayne williams, about to turn 23. a self-anointed music talent scout who slept days and roamed the city at night. mccomas invited williams over to his car. >> he got in the car and i said, do you know why we're here? and he immediately said, yes, it's about the missing children. that kind of stunned me and i said, what do you know about that? he said, i don't think that the various news agencies are covering it adequately, do you? >> two weeks later, this headline would break the news of that night on the bridge. wayne williams would be sent to prison to serve two life sentences for murder. at first glance, he hardly looks like a serial killer. not much more than 5'1/2" feet tall, barely 150 pounds. now in his 50s, and growing bald. >> the bottom line is nobody ever testified or even claimed that they saw me strike another person
