From your link:

"The state’s protocol calls for a secondary set of drug syringes to be administered "if the inmate is not deceased" after the first set. The protocol does not specify what should happen if the inmate remains alive after the second set."

But if they find no one tampered with the drugs, I'd say her sentence should be commuted to life. If the drugs weren't tampered with, it's far too likely that God is sending a message about her sentence to try to execute her again.

Also if the drugs weren't tampered with, somebody ought to study her system and find out why she didn't die. There could be a medical cure in it for something.
