You are wrong!
Jim,
I am sorry but you are wrong. I live very close to that location and what appears on a map is very different to reality. The House itself is built on the top of what is really a cliff. The land to the south is 30 or 40 feet below the house which stands out as a landmark over the nearby M32. The rest of that land is steeply sloping until you get to the bottom which is a long way from the house. THEN you would have to work your way around the side of the fortress like building to gain access to the flat landscaped area to the North of the House. There is simply no access from the south and the apparent grassland that appears on the map is way outside the slope limits of any helicopter.
I have no knowledge of any of the participants and really no interest in the affair but your scenario was so far off beam that it had to be answered.
