Corsicana (WBAP/KLIF) – Police in Corsicana, some 60 miles south of Dallas, are investigating a triple homicide. They got a call over the weekend from a woman who said her sister and her sister’s estranged husband were arguing, and he had a gun. Nancy Castillo told the 9-1-1 dispatcher she was trying at that moment to get her sister’s children out of the house through a window. Then the line went dead. Police found Castillo’s body lying near a bedroom window. They found her sister’s body on the back patio. Then they found the estranged husband’s body inside the house. Evidence indicated he shot the two women, then himself. The children were all O.K.
