Died: June 2, 2025.
Age at death: 6.
Cause of death: Gunshot.
Location: Florencio Varela, Buenos Aires Province, Argentina.
Disability: Autism.

Details:
Esteban lived with his parents in a suburb of Buenos Aires. His father was a lathe operator who worked in Munro, and his job took him away from the family for twelve hours a day. Esteban’s mother stayed home with him.

Unfortunately, Esteban’s mother was struggling with depression. It ran in the family; his grandmother had died by suicide. She was getting treatment, but, from the testimony of neighbors and friends, was “tired of caring for [Esteban],” and argued constantly with her husband over his long work hours.

Esteban and his mother were found dead from gunshot wounds. Investigators believe she shot him while he was asleep or watching TV, after which he took about five hours to die from a head wound. After shooting herself twice, Esteban’s mother died as well. She left a suicide note in which she blamed her husband for having to travel, saying, “We won’t beg you for more.”
