TOPEKA, Kan. - A spokesman for the Kansas prison system says the agency was already planning to review the state's execution process before a botched execution in Oklahoma. Corrections Department spokesman Jeremy Barclay said Wednesday officials will consider which drugs will be used in lethal injections and steps in administering them as an execution nears. But Barclay said an execution isn't likely for at least several years. Kansas enacted its current capital punishment law in 1994 but has yet to execute any convicted murderers. Oklahoma on Tuesday started executing convicted murderer Clayton Lockett but halted the procedure, and he later died of an apparent heart attack. Barclay said Kansas has no supply of lethal injection drugs because any current supply would likely expire before an execution was scheduled.
