The Fourth of July celebration turned into tragedy late Wednesday night when fireworks apparently caused a fire at a trailer house north of Henryetta.
According to fire department officials, a fireworks display is believed to have discharged into an open window of a trailer house starting the blaze.
The fire was said to have been contained to the front of the trailer although the rest of the building sustained major smoke and water damage. The residents of the trailer were not home at the time of the fire.
Four rescue dogs inside the trailer died from the fire.
Fire chief David Bullard said this was the only problem reported during the holiday.
