From the above article
Those who visit the gravestone, however, will notice something highly unusual. While on most graves there is an inscription of two dates — when the person was born and when he or she died — on Terri's there are three.
Here's exactly what the grave says:
Born December 3, 1963
Departed this Earth February 25, 1990
At Peace March 31, 2005
The whole world knows that she died on March 31, 2005. National and global media were present at the scene for days, covering every detail. Media were present again when I preached at her funeral mass. We know when she died.
But her gravestone has become a pulpit for the euthanasia movement. Those who killed her are now using her grave as a platform for their twisted ideology. What they are trying to say is that once her brain was injured in 1990 and she was no longer functioning like most of us, she wasn't one of us anymore. She "departed this earth."
