A towering Denny's Restaurant sign in central Kentucky fell on a car during high winds, killing a woman and injuring her husband and daughter.

The sign partially crushed their car when it fell Thursday from a pole near the Denny’s parking lot off Interstate 65 in Elizabethtown.

Lillian Curtis, 72, was in the back seat and suffered a "catastrophic" head wound, her granddaughter Amy Nichols told news outlets. The Jefferson County Coroner’s Office said she died of blunt force injuries.

They were on their way home to Columbia from Louisville when they pulled off the highway, she said.

Elizabethtown Police Detective Chris Denham said intense wind gusts are believed to have contributed to toppling the sign. A crane was brought in to remove it; crews said it weighed about 1.3 tons. It was permitted to be 80 feet off the ground, the News-Enterprise reported.

Wind gusts in the area reached as high as 49 mph on Thursday, the National Weather Service in Louisville said.
