did a great job. and i feel that if i've don't do everything i can to help find their real child, then i am not doing my job as a son. >> that is a thriller novel. that's unbelievable. >> two incredibly sad stories. now he has no idea where he really came from. he turned up at a supermarket. his entire family who knows where they were. he was abandoned. >> some where out there is paul fronczak. >> this other child taken from his mother's arms. nobody knows if the child ended up, grew up, safe. or its destiny ended up being. so here is what is crazy about the way things used to work 49 years ago. police, they connected him to the family back in chicago because they said that he, he had the same kind of pointed ears. >> pointy ears. >> pointy ears. the age matched as the kid had gone missing. that was enough for them to be okay. here you go. no dna testing. not at all. no blood test.
