Search and rescue teams in Alabama are using dogs and heat-detecting drones to search for victims of the deadly tornado that tore through the southeastern part of the state, as new drone video and photos show the scale of the devastation.

Lee County Sheriff Jay Jones said Tuesday at a news conference at least 23 people were killed and 90 were injured when the giant EF4 twister with 170 mph winds hit the rural community of Beauregard, and seven or eight people are still missing.

The death toll has not yet climbed from 23 as of Tuesday morning, according to Lee County Coroner Bill Harris. All 23 victims have been identified, and range in age from 6 to 93-years-old. One family lost at least seven people, according to Harris.

"It's a tragic situation," he told reporters.

The tornado impacted what the sheriff described as a rural area that had a lot of mobile homes and manufactured-type housing. The twister created a debris field that spread over hundreds of yards, according to Jones, with some debris being thrown a half-mile away.

Harris said that three children, ages 6, 9 and 10 were among the dead in Sunday's tornado.

The full list of victims were identifed as: Armondo (AJ) Hernandez, 6; Charlotte Ann Miller, 59; David Dean, 53; Emmanuel Jones, 53; Eric Jamal Stenson, 38; Felicia Woodall, 22; Florel Tate Stenson, 63; Irma Gomez-Moran, 41; James Henry Tate, 86; Jimmy Lee Jones, 89; Jonathan Marquez Bowen, 9; Maggie Delight Robinson, 57; Mamie Roberts Koon, 68; Marshall Lynn Grimes, 59; Mary Louise Jones, 83; Mykala Waldon, 8; Raymond Robinson Jr, 63; Ryan Pence, 22; Sheila Creech, 59; Taylor Thorton, 10; Tresia Robinson, 62; and Vicki Braswell, 69.

Anyone with the last name Robinson, Tate or Stenson are among the family of seven that was killed, officials told Fox News.

Authorities said that crews were  "basically using everything we can get our hands on" to comb through what was left of homes.

"As the day goes on, there is hope we can transition from a search and rescue to a recovery status," Jones told reporters.

Jones said dogs were being brought in from across the state, in addition to dogs equipped with "infrared capability to detect heat signatures."

"Our son found him. He was done and gone before we got to him," an emotional Dean told the AP. "My life is gone. He was the reason I lived, the reason that I got up."

Chris Darden, meteorologist-in-charge at the NWS' Birmingham office said at a news conference it was the deadliest tornado in the United States since the twister that hit Moore, Oklahoma in 2013. The storm had a track of at least 70 miles, "well into Georgia," according to Darden.

Alabama Gov. Kay Ivey said the tornado-ravaged area is a "tight-knit" community of people.

"We lost children, mothers, fathers, neighbors, and friends," she said.
