US state police said a woman is accused of cutting her sleeping husband's neck and shoulder with a power saw.
Officers in Everett, Washington state, who arrived at the home said they could hear the man shouting: "You tried to cut my head off. You're going to jail."
The Daily Herald reported the 43-year-old woman appeared in court on a charge of domestic violence assault and a judge kept her bail at 250,000 US dollars. The newspaper did not identify her.
Police said the woman told officers she grabbed the saw because an intruder escaped out of her daughter's window.
Sergeant Robert Goetz said there was no evidence of an intruder and a child lock prevented the window from opening more than a few inches.
The 36-year-old man was treated at a hospital.
