Eian H. Santiago was 3 years old when he died on October 17, 2015, after being accidentally shot in the head in his family’s Humboldt Park apartment in Chicago. The boys were being supervised by their grandfather, who was in an upstairs unit and heard the gunshot; the grandfather carried Eian to Norwegian American Hospital and Eian was later transferred to Mount Sinai Hospital, where he was pronounced dead.

Eian’s father, Michael Santiago, 26, did not have a concealed carry license or FOID card, had purchased the revolver after being labeled a snitch, and warned his older son the gun was for adults only. Michael Santiago pleaded guilty to endangering the life or health of a child and received two years probation; he had been released on bond in the days after the shooting.

Does anyone have information about safety measures or witnesses from the Humboldt Park area that could shed more light on how the firearm was stored that day?
