Families are still recovering from last week's winter storm, and the power outages that led to people searching for ways to stay warm led to hundreds of calls regarding carbon monoxide poisoning.
Fire departments in Harris County alone responded to 475 carbon monoxide calls last week, according to the county's fire marshal.
Like millions of Texans, Etenesh Mersha lost power during the storm. In order to charge her phone, she turned on her car in an attached garage, leading to suspected carbon monoxide poisoning.
"She's very nice, and her husband is very nice," said Etenesh's cousin, Yetimwuha Wolde. "She visits us every time, and she calls us every time. She brings us [gifts] every Christmas for my kids."
Etenesh left the car running, and by the time help arrived, she and her daughter, Rakeb, died. Her husband and 8-year-old son were rushed to the hospital.
