Why was he even near this baby? I guess the authorities just wanted to keep the family unit intact./
But then it doesn't make much sense here:
So do we assume he didn't live there and came to the house? If my husband/SO was volatile and showed a propensity to harm a child, like this guy, I wouldn't let him near my kid/s or the house. But then I don't know all the particulars. I will wait to find out the details of this very tragic event. I hope God will heal the hearts broken from this horrible incident.
