The neighborhood surrounding a Texas fertilizer plant that erupted in a thunderous explosion is gone, and the residents here know they’ve lost more than the buildings that went up in flames.

Even as investigators were tight-lipped about the number of dead from the blast — authorities say more than 160 are injured but have not yet released a firm death toll — the names of the dead were becoming known in the town of 2,800, even if they hadn’t been officially released.

Believed to be among them is a small group of firefighters and other first responders who may have rushed toward the fire to fight it before the blast. At a church service at St. Mary of the Assumption Catholic Church on Thursday night, the mourning was already starting.
