I believe Texas holds the record for executions.

Injection executions ran out of prescribed life-ending substances by physicians. (Hippocratic oath controversy) They tried other things that failed or tortured but it has dropped out of the news. I wonder if they are using Fentanyl or some other secret concoction.
