Lisa Montgomery became the first woman executed by the federal government in 67 years early Wednesday.

Montgomery, 52, was executed by lethal injection at the U.S. Penitentiary in Terre Haute. Her time of death was 1:31 a.m., seven and half hours after her originally scheduled time of execution, according to the Associated Press.

As both sides filed appeal after appeal to tip the scales in their favor, Montgomery spent her final moments in a cell within the brick execution building just steps away from the execution chamber.

The U.S. Supreme Court cleared the way for Montgomery’s execution with a pair of orders issued just before midnight.
