Catelin Powers said she was driving with her children nearby when she saw a column of smoke near her house, so she drove to investigate.
”When I got closer to the house, I saw smoke pouring out from the very top of the house, which looked like maybe the attic,” she told The Associated Press.
Two men and a woman on her phone were standing in front of the house, Powers said, when another man emerged from the front door dragging an apparently unconscious, unresponsive woman.
“Her arms were flopped to her sides,” she said.
”She was in either very short shorts or underwear and a tight shirt,” Power said.
She described the woman as having a tan complexion “and looked maybe to be mid-twenties.”
Suspecting the woman was dead, Powers said she drove on so her children would be spared the sight.
Broken Arrow is Tulsa’s biggest suburb, with almost 115,000 residents.
The US Bureau of Alcohol, Tobacco, Firearms and Explosives was assisting in the investigation, he said.
