Oklahoma's attorney general says the state does not have all of the lethal drugs necessary to carry out an execution set for Thursday.
Despite the drug shortage, state lawyers are fighting an attempt by two inmates to delay their executions while they seek more information about Oklahoma's execution procedures.
The state says it is still working to obtain execution drugs and will change protocols if necessary to execute Clayton Lockett this Thursday.
The attorney general's office said in briefs filed with the Oklahoma Court of Criminal Appeals on Monday that a deal to obtain pentobarbital and vecuronium bromide from a pharmacy had fallen through.
Pentobarbital is a sedative, vecuronium bromide is a muscle relaxant and a third drug stops the heart.
Charles Warner is to die March 27.
