MAYFIELD, Ky. (AP) — Workers on the night shift at Mayfield Consumer Products were in the middle of the holiday rush, cranking out candles, when a tornado closed in on the factory and the word went out: “Duck and cover.”

Autumn Kirks pulled down her safety googles and took shelter, tossing aside wax and fragrance buckets to make room. She glanced away from her boyfriend, Lannis Ward, and when she looked back, he was gone.

On Sunday, he was among scores of people missing and feared dead in the rubble of the factory.

With Kentucky’s governor warning that the state’s death toll from the tornado outbreak Friday night in Mayfield and other communities could exceed 100, Kirks and others waited in agony for news of their loved ones while the rescue effort grew bleaker by the hour.

“Not knowing is worse than knowing right now,” she said. “I’m trying to stay strong. It’s very hard right now.”

Forty of the 110 people who were inside the factory were pulled out soon after the twister struck, authorities said. Rescuers had to crawl over the dead to get to the living at a disaster scene that smelled like scented candles.

But by the time churchgoers gathered Sunday morning to pray for the lost, more than 24 hours had elapsed since anyone had been found alive. Instead, crews recovered pieces of peoples’ lives — a backpack, a pair of shoes and a cellphone with 27 missed messages were among the items.

“It’ll be a miracle if we pull anybody else out of that. It’s now 15 feet deep of steel and cars on top of where the roof was,” Gov. Andy Beshear said on CNN. “Just tough.”

Kentucky was the worst-hit state by far in an unusual mid-December swarm of twisters across the Midwest and the South that leveled entire communities and left at least 14 people dead in four other states.

“I can tell you from reports that I’ve received I know we’ve lost more than 80 Kentuckians. That number is going to exceed more than 100,” Beshear said.

Four twisters hit the state in all, including one with an extraordinarily long path of about 200 miles (322 kilometers) long, authorities said.

“I’ve got towns that are gone, that are just, I mean gone. My dad’s hometown — half of it isn’t standing,” Breshear said of Dawson Springs.

He said that going door to door in search of victims is out of the question in the hardest-hit areas: “There are no doors.” With afternoon high temperatures forecast only in the 40s, tens of thousands of people were without power, and about 300 National Guard members were going house to house, checking on people and helping to remove debris.

Kirks said she and her boyfriend were about 10 feet apart in a hallway when someone said to take cover. Suddenly, she saw sky and lightning where a wall had been, and Ward had vanished.

“I remember taking my eyes off of him for a second, and then he was gone. I don’t know where he went, don’t have any idea,” she said.

Kirks was at a ministry center where people gathered to seek information about the missing.

“It was indescribable,” Pastor Joel Cauley said of the disaster scene. “It was almost like you were in a twilight zone. You could smell the aroma of candles, and you could hear the cries of people for help. Candle smells and all the sirens is not something I ever expected to experience at the same time.”

The tornado that carved the path of destruction in Kentucky touched down for an extraordinary and potentially record-breaking distance of more than 200 miles (320 kilometers). Eleven people were reported killed in and around Bowling Green alone.
