Having suffered a heart attack in September, 76 year old, legally blind and wheelchair-bound Clarence Ray Allen had asked prison authorities to let him die if he went into cardiac arrest before his execution, a request prison officials said they would not honor. "At no point are we not going to value the sanctity of life," said prison spokesman Vernell Crittendon, "We would resuscitate him, then execute him."--Houston Chronicle, January 12, 2006
Update: It looks like the "then execute him" part of the quotation was added as this tidbit has been passed around. In the original quote, here, it is implied but not stated by the prison spokesman.
