At least two families have filed lawsuits against Oncor, blaming the company for the deaths of two elderly Texans.
The family of a 68-year-old Whitney man says he was found with frostbite in his home that was without power for days during the coldest of last month's cold snap.
And a 73-year-old San Saba woman says she died for lack of oxygen when the power failures left her breathing machine useless.
