Arizona prepares for death row executions with gas once used by Nazis
CBSN
After nearly seven years, Arizona will begin to execute death row inmates again – and has purchased the ingredients to make hydrogen cyanide, or HCN, a lethal gas once used by Nazis.
Zyklon B, a powerful insecticide, is a carrier for hydrogen cyanide, which was used to kill Jews at Auschwitz, according to the Jewish Virtual Library. HCN, which is extremely poisonous to humans, is the cause of death following the application of Zyklon B. An average 6,000 Jews were killed each day using Zyklon B at the Auschwitz II killing center, according to the U.S. Holocaust Memorial Museum.On Nov. 13, 2016, Dr. Eric "Scott" Sills, a renowned California fertility doctor, called 911 and reported finding his wife and business partner Susann Sills unresponsive at the bottom of the stairs. An initial investigation revealed some evidence that was consistent with an accidental fall. But as "48 Hours" correspondent Tracy Smith reports, other evidence pointed to something more sinister. DETECTIVE: How do you know she — she got an email? MARY-KATHERINE SILLS: I woke up and my dad was just like on the covers just laying there like there wasn't enough room to get in I guess. So, he was just laying there.
