Some reports say the execution today took over 15 minutes. A new mixture of midazolam and hydromorphone. I don't know how long executions took with Pentobarbital. Pentobarbital can no longer be exported to the US due to Danish law. I remember that one guy took potassium cyanide in the courtroom and it only took 5 minutes for that to take place, but it did look painful.
