Arizona tried to illegally import an execution drug not approved for use in U.S.

Arizona tried to illegally import a lethal injection drug that is banned in the U.S., but the state never got the drug after federal agents halted the shipment at Phoenix airport. The Associated Press has the documents, and the resulting scoop.

Arizona paid nearly $27,000 for sodium thiopental, an anesthetic that has been used to carry out executions but is no longer manufactured by FDA-approved companies, the documents said. When the drugs arrived via British Airways at the Phoenix International Airport in July, they were seized by federal officials and have not been released, according to the documents.

"The department is contesting FDA's legal authority to continue to withhold the state's execution chemicals," state Department of Corrections spokesman Andrew Wilder said Thursday.

Arizona and other death penalty states have been struggling to obtain legal execution drugs for several years after European companies refused to sell the drugs, including sodium thiopental, that have been used to carry out executions. States have had to change drug combinations or, in some cases, put executions on hold temporarily as they look for other options.

The Arizona documents obtained by the AP were released as part of a lawsuit against the corrections department over transparency in executions. The AP is a party in the lawsuit.
