At Least 21 Cold-Related Deaths Reported Amid Polar Vortex

There have been freezing temperatures in all 50 states

The so-called "polar vortex" of dense, frigid air that spread across the country shattering temperature records is being blamed for at least 21 deaths.

Authorities reported at least 21 cold-related deaths across the country since Sunday, including seven in Illinois and six in Indiana. At least five people died after collapsing while shoveling snow, while several victims were identified as homeless people who either refused shelter or didn't make it to a warm haven soon enough to save themselves from the bitter temperatures.
