Louisiana Governor Jeff Landry said crime victims and their families have waited too long for justice in the form of death penalty executions.

Governor Landry announced that the La. Dept. of Public Safety and Corrections has finalized and implemented an updated protocol that allows for the sentences of inmates on death Row to be carried out.

That difficulty was part of the reason Louisiana lawmakers legalized the use of nitrogen gas and the electric chair as methods for carrying out death sentences last year. At the time, a group of Jewish citizens appealed to lawmakers to reject the use of gassing, saying it evoked the gas chambers used during the Holocaust.

Gov. Jeff Landry announced Monday that the state had developed a protocol for executing people with nitrogen gas, allowing it to resume executions after 15 years. At least three district attorneys have since sought death warrants.
