Three sisters are suing the Nevada Donor Network. They say nonprofit was misleading when a representative convinced them to allow tissue to be harvested from their mother.  The Las Vegas Review-Journal reports Kristine Fagone and her sisters say, when their mother died unexpectedly, the Nevada Donor Network, called to ask if it could harvest tissue from her body. Fagone says they planned an open-casket funeral and a Donor Network representative promised the procedure would not be noticeable, but when the funeral came, Fagone says her mother’s body was “substantially disfigured.”
