The many deaths of Arístides(Las muertes de Arístides)

Arístides died of a gunshot when he was 19 years old, while he was doing his Military Service in the Cuban Navy. He was shot in the chest at close range by the soldier who was supposed to relieve him in duty, with a Makarov PM handgun made in USSR. There are no images of him; just a letter he wrote to his sister a few hours before dying, whose reply never came to be.
