LUTHER, Okla. — Residents who sifted through their charred belongings Saturday found little that was salvageable after a roaring wildfire that may have been deliberately set swept across the dry Oklahoma landscape.

The fire destroyed nearly five dozen homes and other buildings in and around Luther before firefighters were able to gain some measure of control overnight. Video from news helicopters showed orange-bright flames flickering in the darkness, and daybreak Saturday revealed a broad path of destruction.

The fire was one of several burning Saturday in Oklahoma, where a severe drought has parched the landscape. Authorities suspect it may have been intentionally set. The Oklahoma County Sheriff's Department said it was looking for someone in a black pickup who was seen throwing newspapers out a window after setting them ablaze.

Department spokeswoman Mary Myers said there were "no arrests, no suspects" but deputies were "working around the clock" to find anyone responsible.

Gov. Mary Fallin toured Luther, hugging residents whose homes and belongings were destroyed by the fire that swept through treetops on 24 mph winds.

"It's heartbreaking to see families that have lost so much," Fallin said after talking with some who were milling around the still-smoking debris that had been their homes.

The fire burned just over 4 square miles, including an area near the Turner Turnpike, which carries Interstate 44 between Oklahoma City and Tulsa. The superhighway was briefly closed Friday and traffic was diverted onto old Route 66, the cross-country highway that brought Luther a glimmer of life before the interstate bypassing the town was built in the 1950s.

On Saturday, those returning to their homes found charred timbers poking from the debris and the burned out shells of refrigerators, washers and dryers.

"It's all gone. All of our family pictures, everything was there," said Victoria Landavazo, clutching a young child in her arms.

Her neighbors, Douglas and Rebecca Kolar, spoke with their insurance agent in front of the remains of their home. Rebecca Kolar saw footage of it burning the night before on television.

"They thought the fire was going behind" the neighborhood, she said. "And then the wind shifted, and it was too quick. We couldn't do anything."

She said she was able to gather her children, three dogs and some family photos before her house and six others on the street caught fire and burned.

Tracy Streeper was working in Oklahoma City, about 40 miles southwest, when she learned the fire was approaching. Caught in traffic, it took her a long time to reach home and then, "once we got here, we had maybe 30 minutes."

She grabbed a few clothes, medicine and her three dogs and left quickly.

"Your adrenaline is running. You're pumped up," Streeper said. "You could just see a wall of flames coming this way. Everything was on fire."

The summer in Oklahoma is shaping up to be much like last year's, with little rainfall, low humidity and temperatures exceeding 110 degrees in many locations. The Oklahoma Forestry Commission said that means it also could be another bad year for wildfires.

"I think it's going to be right up there, (as among the worst) in memories, at least," said Michelle Finch-Walker, an agency spokeswoman. She predicted the number of fires could end up being similar to last year, when the agency fought about 1,800 wildfires.

Utility crews that had shut off service to much of Luther spent part of Saturday morning restoring power to homes that weren't damaged — though Fallin said much of the town was still covered by an evacuation order because of the danger from downed power lines and other infrastructure.

Other fires burned near Mannford, Noble and Geary. Local officials said the Mannford fire had charred about 78 square miles in Creek County and still wasn't under control. Creek County Commissioner Newt Stephens warned residents to get out and not come back because a change in wind direction could spread it further.
