On the day that Louisiana's first execution in 15 years is scheduled to take place, attorneys for the inmate are hoping for a last-minute court ruling to halt the death penalty from being carried out. Jessie Hoffman Jr., 46, is scheduled to be put to death Tuesday evening using nitrogen gas, which would be the first time Louisiana has ever used the method. Nitrogen gas has been used just four other times to execute a person on death row in the United States, all in Alabama — which is the only other state where there is a protocol for the specific method.
