Aside from staff, as many as 25 individuals may witness the execution from three observation rooms that surround the execution chamber, according to the department memo. The witnesses include relatives of the victims, representatives for the state, news media and individuals selected by Gardner.
Once the witnesses are in place, the prison warden will open the curtains on the observation room windows. Gardner will be asked for any last words.
Then, after a final check for a stay with the Utah attorney general's office, comes the order to the executioners, who fire from a distance of about 25 feet.
The gunmen stand behind a wall cut with a gunport, their rifles bench-rested to assure accuracy, DeLand said.
The guns are handed out randomly to the officers. One will be loaded with a blank, so no one will know who fired the fatal shot. By law, the identities of those selected for the firing squad remain secret.
