Arizona ‘refurbishes’ its gas chamber to prepare for executions, documents reveal

The corrections department has spent more than $2,000 on ingredients to make cyanide gas, the same used in Auschwitz

The state of Arizona is preparing to kill death row inmates using hydrogen cyanide, the same lethal gas that was deployed at Auschwitz.

Documents obtained by the Guardian reveal that Arizona's department of corrections has spent more than $2,000 in procuring the ingredients to make cyanide gas. The department bought a solid brick of potassium cyanide in December for $1,530.
