I may have missed this - did the grandparents own this home or were they renting it? If they were renting, getting rid of everything a few days before the end of the month makes sense. I can't find the house listed for sale anywhere.
ETA: I found another article where a neighbour was quoted as saying the Liknes had recently sold this home.
