Wwyd dd friend across the street.

So my oldest plays with a little girl she goes to school with who also happens to live across the street. Well they get along great. Its the adults in the home who I have a issue with. A few weeks ago when dd was over $2 went missing. Before even looking they told her if they cant find it she will no longer be welcomed at there home... Well not even 5 min later they found it behind a dresser. Guess it fell off from the kids playing and knocking it down behind it. What I didnt get was why they jumped right to accusing my dd instead of looking first. I didnt let her go over for a couple weeks after that... Well today she tried to go over to play and one of the adults open the door see its her and shut it in her face... She came home in tears. Ive come to the decision not to have her go over there anymore. Not only that there dd is never allowed at our home to play. Just feel its really unfair and wrong to treat a 9 year old like that. But now my dd is heartbroken because I told her I dont want her over there anymore. Its her only friend on our street after her bff moved away two months ago. This just sucks because I feel so bad for dd. But dont want her over at a house where if something goes missing she will get blammed or getting the door shut in her face for simply seeing if she can play for a hour or two.
