Diana Martinez Rangel was the epitome of strength, resilience and kindness to her family. She'd learned to navigate the world without her hearing, raised six children, persevered through multiple heart attacks and stuck to a strict dialysis regimen for the past seven years. Inside her Manor home, weeks after the mid-February winter storm, her son Miguel Rangel said he was still in shock that she had died. “It just hurts because she wasn’t supposed to go this way,” Rangel said. In stage 4 kidney failure, Martinez Rangel needed dialysis treatments three times a week. After the freeze left millions across the state without electricity or water, the dialysis center she depended on had to shutter. The day before they reopened, she died.
