June marked the end of a three-year long legal battle to tighten up Arizona’s execution laws, but even after the state reached an agreement, the fate of those on death row is still uncertain.

According to the Bureau of Justice Statistics’ most recent data – accounting for prisoners under sentence of death as of December 31, 2015 – Arizona did see its first uptick in death row inmates in five years with the addition of two inmates in 2015.
