I lived in Quincy, although I didn't know her, and have several Facebook friends who did know her. The family issues were taken off Judici.com when Becky was found deceased, mainly for privacy issues affecting their son, <modsnip - sleuthing and discussing the social media of family members is not allowed> actually, it was the father-in-law who filed a protection order against Becky! That was also dropped due to lack of evidence.
As for "something happened to this guy", it sounds like the same story, all over again: Woman in "caring professions" (like, for instance, a nurse) meets a very bad man, and marries him and has multiple children with him, because she thinks she can change him. Yeah, it sounds like he was the Big Man On Campus when he was in high school, and never moved beyond that. This does not in any way mean that she deserved her fate, and her children definitely don't either.
(Believe me, it's not just strippers who send their child support money to their incarcerated boyfriends! Saw that more than once.)
