Missouri Gov. Jay Nixon has refused to halt the execution of white supremacist serial killer Joseph Paul Franklin, calling his crime in Missouri a "cowardly and calculated shooting."

Nixon's office announced the decision Monday afternoon.

A month ago, St. Louis Public Radio reported on the questionable manner in which the state of Missouri got ahold of its potential execution drug. Now Missouri has a new plan to go ahead with two upcoming executions, but the process is anything but open.

Two weeks ago, Gov. Jay Nixon instructed the Missouri Department of Corrections to come up with a new procedure for carrying out lethal injections.

On Tuesday, the department announced that it had chosen a new execution drug: pentobarbital. But the state also made a change that will end up making it harder, if not impossible, to know where the drugs come from.

On Tuesday, the Missouri Department of Corrections announced that it had selected a new drug for upcoming executions: pentobarbital.

The change comes following criticism of the questionable methods Missouri had obtained the drug it had previously planned to use, as well as concern that its use could harm hospitals throughout the U.S. The state had planned to use a common anesthetic named propofol, which has never been used to carry out an execution.
