I believe MS has twice inadvertently admitted -- once in sworn testimony, once on LKL -- that he was killing Terri to spite the Schindlers. I didn't save the references, but assume that they can be located. If anyone has them set aside, please post or let me know.
Of course on a more recent LKL, after the usual lies about Terri wanting to die, he tripped up again and admitted, "We didn't know what Terri wanted, but this is what we want... "
He basically said he was going to kill Terri no matter what.. basically that no one was going to stop him.
Michael Schiavo said to Larry King "I did this to my parents and I'm not gonna stop now." I taped it. That's my recollection of my recording.
