Nevada's highest court won't immediately lift a stay that has delayed a convicted murderer's execution.

While the U.S. Supreme Court on the 16th upheld a lethal injection method that's similar to Nevada's, the state's highest court won't immediately lift a stay that has delayed a convicted murderer's execution. State Supreme Court spokesman Bill Gang said justices will review the U.S. Supreme Court ruling that upheld Kentucky's use of lethal injections to determine its effect on pending Nevada cases, including that of William Castillo. "There's not just an automatic dropping of the (Castillo) stay," said Gang, adding that he couldn't say how long the state high court's review would take. The state Supreme Court halted Castillo's execution on October 15, just 90 minutes before he was to get a lethal injection. Castillo was sentenced to death in 1996 for the murder in 1995 of Isabelle Berndt.
