The brothers, Ryan and Joshua Hall, had muscular dystrophy and were dependent on the breathing ventilators for life support, Fox 40 reported. On Tuesday night, a widespread power outage hit the area, prompting their mother to call authorities for help.
When sheriff's deputies arrived, they found the brothers in distress and immediately administered CPR, but the brothers eventually died.
"They had backup systems that didn't work, so it looks like there may have been a failure of equipment there," neighbor Steven St. Sure told Fox 40. "I mean, power outages are always a possibility, especially up here."
The deaths of the brothers saddened neighbors in the small town east of Stockton.
“I heard and I just started crying,” neighbor Kayte Dollens said.
Another neighbor, Megan Dollens, told ABC News 10 she couldn't imagine the family's pain.
"I honestly don't know what to think about this because it's awful," she said. "I can't imagine what their parents are thinking."
