Here's how many Texans died after deregulation caused massive power outages during winter snow

At least 57 people died in Texas as a result of last month's winter storm, according to preliminary data the state health department released Monday.

The largest number of deaths — at least 25 — occured in Harris County, the Texas Department of State Health Services reported.

The deaths occurred in at least 25 counties between Feb. 11 and March 5, the state agency said. The majority of verified deaths were associated with hypothermia, but health officials said some were also caused by motor vehicle wrecks, "carbon monoxide poisoning, medical equipment failure, falls, and fire."

The preliminary data is "subject to change" as state disaster epidemiologists gather additional information and additional deaths are verified, the agency said. The information will be updated weekly, it said.
