GRANBURY, Texas (CNN) — Rescue crews searched Thursday for seven people missing after overnight tornadoes struck North Texas, killing at least six.

“We’re still working to identify people,” Hood County Sheriff Roger Deeds told reporters about the fatalities, all of whom were adults.

It was not clear whether the toll would rise. Rescue crews had walked through one subdivision in the city of Granbury “over and over and over again,” he said. “I’m confident we haven’t left anybody behind, but we’re still checking.” Granbury is located 40 miles southwest of Fort Worth.

The six victims were located in a Habitat for Humanity neighborhood of about 110 homes — most of which were destroyed — called the Rancho Brazos subdivision, the sheriff said. That is where the missing were last seen, too, he said.

Three people were taken to an area hospital, and 13 others were taken to hospitals in the Dallas-Fort Worth metroplex, he said.

At least 10 tornadoes touched down overnight in the area, the National Weather Service said.

“The main concern is life safety and finding any victims that still need our help, making sure we tend to those victims and their pets, too,” Deeds said.

There were reports of homes in Granbury being flattened with people inside, Hood County Judge Darrell Cockerham said.

In nearby Ellis County, a suspected tornado knocked out power in the city of Ennis at about midnight, said Steve Howerton, city manager.

“Several buildings in the downtown historic district have been seriously damaged,” he said.

“There are a lot of traumatic injuries,” said Donna Martin, a worker at a local veterans' organization. “My husband told me that a car was lifted in the air. It just came in and hit so fast.”

City officials were sending school buses to affected neighborhoods to help with evacuations.
