Very sad when family relationships break down to this degree.Some disagreement can be considered normal and worked out usually.

To attack your parents is fundementally wrong no matter what feelings are involved. To steal from anyone is really wrong too.

I have to wonder about your daughters general mental condition and age. Sometimes a total parting is unavoidable I suppose. Still a kind of really sad occurance.. Is she involved in the modern drug culture? Something like that would explain a lot. Still not justifying the behaviour though.
