Where is Michael R. Davis today?

in 1963, my sis-in-law committed a crime (as a teen), and was sent to Geniva School for Girls. while incarcerated, she was taken to chicago research hospital, and gave birth to a baby boy. she signed papers for his health-care (later found out they were adoption papers). they then took her back to the school to finish her sentence. She had stolen a check, less than $100, from her friend's mailbox. mail theft=federal offense. she was a juvanile, not allowed to keep her baby, and has been searching for him since. he would now be 42 years old. a teenage federal crime cost 2 life sentences. hers & his! she really wants to find him. does anybody know him?
