May 1992… Michael and the Schindlers stop living together
January 1993… Michael recovers $1 million settlement for medical malpractice claim involving Terri's care; jury had ruled in Michael's favor on allegations Terri's doctors failed to diagnose her bulimia, which led to her heart failure; case settled while on appeal
March 1994… Terri is transferred to a Largo nursing home
May 1998… Michael files petition for court to determine whether Terri's feeding tube should be removed; Michael takes position that Terri would chose to remove the tube; Terri's parents take position that Terri would chose not to remove the tube
So, it takes another five years after the settlement is received for Michael to petition the courts.
My point - it's not surprising that before he won the lawsuit, he was a bit more attentive. And while it may have taken five years for him to petition the court to remove the feeding tube, it was only a few months after award of the settlement that he began to deny care.
The settlement was awarded in Nov 92. In February 93, Michael denied Terri therapy and placed a DNR on her chart.
