Names of Alabama tornado victims released: Ages range from 6 to 89

Authorities have released the names of the 23 people, including four young children, who were killed when powerful tornadoes ripped through Lee County, Alabama, on Sunday, leaving the close-knit community of Beauregard in mourning.

This storm brought the highest tornado death toll in the United States since 2013, according to the National Weather Service.

The victims’ ages range from 6 to 89, according to the coroner.

At least seven of the victims were from two families who are related by marriage and lived a few houses apart, Coroner Bill Harris said Tuesday.

Those killed lived in roughly a one-square-mile area of the town of Beauregard, a resilient, community-oriented town of roughly 9,000, said Lee County Sheriff Jay Jones.

Preliminary reports indicate the deadly twister reached an EF-4 category with winds estimated at 170 mph.

As of Tuesday, about seven to eight people remained unaccounted for, said Jones.
