From Businessman Offers $1 Million to Keep Terri Schiavo Alive:
"We are here today to announce that our client, Robert Herring, Sr., is making an offer to Terri Schiavo's husband, Michael Schiavo, which could save Terri's life.
Terri Schiavo is currently in a coma in Florida. Michael Schiavo has asked the court for permission to disconnect her feeding tube, which would result in her death. Terri's parents, Bob and Mary Schiavo, have opposed the request. After a long court battle the court has set March 18, 2005 for the removal of Terri's feeding tube."
