teresa's granddaughter helana was diagnosed with cancer. ray kotomski did the right thing. he and teresa were soon spending alternating weeks in a cleveland hospital where baby helena was being treated. ray even shaved his own head when the little girl lost her hair from the chemo. it sounds like he really sort of bonded with helena. >> absolutely, yeah. he had mentioned to a family member that he felt that god put him here exactly at that time for a reason, and it was to take care of her. >> reporter: helena's cancer went into remission, but ray and teresa's relationship suffered collateral damage. according to teresa's family, the strain of becoming a father again had made ray toxic. he was, they said, angry and drinking more beer than usual. >> mom was scared, so mom couldn't tell him to cut back on his drinking. he was stressed out, or something was going on there. >> reporter: sounds like a pretty unhappy guy. >> totally. >> reporter: ray's family says he was fine, and that his drinking was never a problem. but by early august 2009, teresa apparently had enough of ray.
