MO Execution Method in Question

The Missouri Supreme Court on Tuesday declined to set execution dates for six condemned killers, saying doing so is “premature” until the courts decide if Missouri’s new execution method is constitutional.

Missouri Attorney General Chris Koster asked the court to set the execution dates in May, the same month the Missouri Department of Corrections adopted a new execution protocol that uses a single drug, propofol. Koster called it disappointing. Propofol, perhaps best known as the drug that killed pop star Michael Jackson in 2009, has never been used as an execution drug. A lawsuit filed by death row inmate David Zink claims its use could violate the constitutional guarantee against cruel and unusual punishment.
