The ongoing investigation involves the fatal shooting of a Greek inmate who was serving a life sentence at Domokos prison. Authorities are particularly focused on the circumstances surrounding the altercation and how a firearm entered the prison premises. This incident raises significant concerns about security protocols within the facility and the potential for violence among inmates, especially given the histories of those involved.

Reports indicate that the violent incident occurred in the early evening at the chief guard's office where the inmate allegedly entered armed with a pistol. The situation escalated as he is believed to have intended to attack the chief guard. In addition to the guard, two high-risk inmates were present: a Bulgarian serving life for the murder of businessman John Makris in 2018, and an Albanian known for his dramatic helicopter escape from custody.

This incident not only highlights the ongoing issues within the Greek prison system regarding inmate safety and security but also spurs questions about potential systemic failures that allow prisoners to possess weapons. The authorities' findings could lead to significant policy changes and a re-evaluation of prison management to prevent such incidents in the future.
