A few minutes before she died, they were told to leave the room by Michael Schiavo, their spokesman said.
How nice of him to deprive them of those last few minutes.
Since Michael has claimed that Terri has no awareness of those around her, why was it so important to Michale that her birth family be kept away at the moment of her passing? Afterall, the benefit of comfort from loved ones at the moment of death is for the one dying. Using Michael's theory, it didn't matter who was there except for the opportunity to gouge the Schindler family one last time.
