>> reporter: and they did. a year later came a baby girl. and sam embraced his role as dad. >> he was like mr. mom, you know. he stayed home and took care of the baby while i worked. >> reporter: if sam had anything to do with cathy's murder, he certainly didn't act like it. he stayed put. living with his wife and baby right down the street from cathy's mom, mary. >> she would sit outside and stare at us, and i felt like she was doing it to make me uncomfortable, and probably him, too. but i'm sure she didn't want him to be happy if she thought that he had anything to do with what happened to her daughter. >> reporter: sam say anything about mary? >> no. no. he would try to tell me to ignore it. >> reporter: i mean, was this like the hatfields and the mccoys? what happened? >> there was no communication, no associations with them, you know. that was basically it.
