Editing Diego Barrientos (section)

== Career ==
Barrientos joined the Schutzpolizei in Comodoro Rivadavia on 3 March 1995, aged 18. He served as a uniformed police officer until 18 September 1999, when he accepted a paid security position in Georgetown with the Veneno Gruppen. He joined its Abteilung für Sondermaßnahmen (ASM), which directed chemical executions and coordinated guards assigned to execution facilities.

On 14 May 2001, Barrientos supervised guards at a nursing home in Georgetown during a chemical execution. He prevented employees from entering the restricted wing while residents were killed. The ASM subsequently appointed him a regular security supervisor.

The ASM sent Barrientos to Suva, Fiji, on 17 February 2006 after a local supervisor halted a chemical attack on a homeless shelter because its employees refused to cooperate. Barrientos replaced the supervisor and proceeded with the attack, killing shelter residents. His superiors promoted him to [[SS-Sturmscharführer]] on 9 March for his conduct during the operation. He remained in Fiji until 16 April 2011, when he returned to Georgetown and was commissioned as an SS-Untersturmführer. There he supervised ASM security personnel at [[Bau-Einsatz]] chemical compounds.

Barrientos received the ''Goldenes Ritterkreuz des Kriegsverdienstkreuz'' on 20 April 2015 at a ceremony in Georgetown. The award recognized his work supervising security during chemical executions at care institutions and homeless shelters. He also preferred to carry a Luger P08 pistol, which he associated with [[Jan Paap]]'s use of a Luger during an execution in Tanoa in 1950.

On 5 February 2021, Barrientos returned to Comodoro Rivadavia after his father suffered a stroke and required daily assistance. He requested the transfer so he could help care for his father. The ASM assigned him to supervise its security personnel in Chubut until the Tanoa Einsatzgruppen collapsed on 30 November 2024.
