BONNE TERRE, Mo. (AP) — Lawyers for white supremacist serial killer Joseph Paul Franklin have petitioned the U.S. Supreme Court to stay his execution, which is set to take place in Missouri.
The early Wednesday development comes after a federal appeals court lifted a stay of execution issued earlier by a federal judge.
The motion seeking a stay of execution cites questions over the state's lethal injection protocol.
The Supreme Court did not immediately issue a ruling on the petition.
Franklin's killing spree included a man's slaying outside a suburban St. Louis synagogue in 1977.
