Bernice King and Martin Luther King, III, are suing their younger brother Dexter in an attempt to get him to open up the books of their famous father's estate. "The lawsuit claims that Dexter King, the estate's administrator, is refusing to provide his two siblings with documents concerning the estate's operations. That includes financial records, contracts and other documents, the lawsuit said. The AP reports that Jock Smith, an attorney representing the elder siblings in the case, said Friday that the decision to sue their brother was not an easy one." [EUR]
