Louisiana is set to put a condemned man to death using nitrogen gas Tuesday evening in its first execution since 2010, which would make it only the second state to administer the controversial method.

Death row inmate Jessie Hoffman's execution marks the first time Louisiana has used the method and is the state's first execution in 15 years.

It was the fifth time nitrogen gas was used in the US after four executions by the same method — all in Alabama.
