boondog, someone else did ask the question but I'm going to ask it again in case you missed it. Is there any police/legal action pending or active against your father-in-law? How was the investigators/responders to the scene towards your father-in-law? Has it changed now that they found a body? Have they confirmed the identity of the body? So many questions...

If you ignored the previous question on purpose because it is sensitive at this stage, I understand. I'll assume you're doing it again if you fail to answer this second question.
