Can an adoption disruption take place if one sibling has already run away and the others are planning to do the same?
Step-grandmother battling cirrhosis that was not revealed in the adoption medical evaluation in order to be eligible to adopt children. She continues to drink and has turned my biological granddaughter's life into a life of servitude and she appears as skin and bones in the last picture I saw of her. Step-grandmother will not allow me to see the children, contrary to original court transcript I purchased, because she does not want me to see how poorly they are doing. My 11 year old granddaughter I had DeFacto status on was adopted out without notification to me constituting a fraudulent adoption by the Social Worker handling the case in CA.
