How very sad! I can understand being distraught after losing your wife, but the children shouldn't suffer. It wasn't their fault. I couldn't see the link on the last article you posted. Did he really admit to it? The baby suffered blunt force trauma, so I assume he did...
""I didn't know how to feel about him, the same day he was born, my wife died," he told the Fox affiliate. "The feelings inside of me, I kind of wanted to push him away, but he's my son, my wife gave him to me."
..... Wow.... That poor baby. At least he's reunited with his mother. My heart goes out to their family. How very, very sad...
