Ex Deputy So and So and the mom are going to prison...(spoilers)
Someone is going to have to answer for that man burned alive on a cross in their backyard, and the missing kid. I don't think the "my son was posessed by a demon" defense will hold up in court.
And coupled with the fact that the mom already has a history of desperately wanting to get away from her husband and she's hooking up with a man who already has been suspected of murder and arson. Hell, they are just as good as convicted.
