A four-year-old boy fell from an apartment window and died in the Concourse Village section of the Bronx on Saturday afternoon.

Gabriel Estevez was on the fourth-floor apartment of a building on East 161st Street while his mother was at the Laundromat, neighbors say. People heard the boy screaming and tried heading to the building in time to catch the boy in case he would fall, but they didn’t make it in time.

The windows of the apartment don’t have window guards but there are radiators right below them, neighbors told NY1. The radiators would make it easy for an unsupervised child to climb up to the window.
