Missouri considering use of gas chamber

Missouri now has a de facto moratorium on executions because a federal district judge has to date refused to approve its revised lethal injection protocol.  Consequently, as this article details, some state officials are talking about using the gas chamber for executions:

In June, a judge halted all executions in Missouri, saying the process is flawed. Now, politicians are exploring other execution options, including bringing back the gas chamber.  In 1965, Lloyd Leo Anderson became the last person to die in Missouri's gas chamber.  That building still stands, old and unused. The law that allows it still exists too, largely forgotten until now.

Several state senators, including one in Kansas City and another in St. Louis, have begun investigating the possibility of resurrecting the gas chamber as a way to circumvent U.S. District Judge Fernando Gaitan Jr.'s ruling that has all executions on hold. Gaitan is requiring that the process of lethal injection be revised. He is requiring an anesthesiologist supervise. So far none has been willing. With no way for the state to comply, legislators are now pursuing other possibilities.
