The American Civil Liberties Union of Nevada has launched a petition to stop the state's first execution in more than a decade.
46-year-old Scott Dozier is scheduled to die by lethal ejection November 14 at the Ely State Prison.
The ACLU is calling it an "experimental execution" because the blend of drugs has never been used anywhere else in the country.
The group posted a petition online this week seeking signatures on a letter asking Governor Brian Sandoval to intervene.
The ACLU says there's a "very real" chance of a botched execution and painful, inhumane death.
