Who did what to whom?

If you've been keeping up with this story, you can probably assign all the players in the hed to their correct slots. If you haven't, you're going to have a bit of trouble. Whose wife -- the dad's or the son's? His son, her son, their son?

The Web version is even more bizarre in a different way: "Mansfield father found guilty in wife's drowning death of baby":

The baby's death by drowning
* The baby's death by wife

Is the hed writer trying to avoid saying that the wife killed the baby, owing to her having been acquitted by reason of insanity? ("Wife's killing of baby" might work.)

We need to back out and start all over on this one.
