SAN FRANCISCO – A federal judge ruled Tuesday that California must change its lethal injection method for the execution of Michael Morales next week because the current mix of drugs may constitute cruel and unusual punishment. U.S. District Judge Jeremy Fogel in San Jose declined to immediately postpone Morales' Feb. 21 scheduled execution, but he ordered the state to either have an expert present to ensure he's unconscious from a sedative or replace a three-drug death potion with a lethal dose of barbiturate.
