The attorney general's office said in a court filing Wednesday that it can no longer try to proceed with the lethal injection of Albert Greenwood Brown this week. It would've been California's first since 2006.
The announcement comes a day after a federal judge blocked the execution, saying he needed more time to evaluate the newly adopted lethal injection procedures.
The state tried to appeal that decision. But after another unfavorable ruling by the California Supreme Court, it conceded that the execution can't happen now.
The soonest that officials could execute Brown is Friday. But by then, their entire supply of a lethal injection drug will have expired.
