The Washington woman on trial this week for attempting to kill her husband while he slept by sawing off his head was convicted Thursday.

Renee Bishop-McKean, 44, was found guilty of attempted murder for the attack, in which she revved up an electric sabre saw over her husband's head while he was asleep, according to ABC News affiliate KOMO. Her husband, Brett Bishop, awoke from the noise and fought off his wife, though she then attacked him with a mallet and hatchet, according to the prosecution. He received cuts and bruises.

Prosecutors told the jury during testimony this week that if Bishop-McKean had turned the saw on just inches closer to her husband's neck, her husband would be dead. She also covered the mattress where he slept in plastic and purchased bleach and trash bags before the attack, they said.

Bishop-McKean's attorney, Ken Lee, told the Everett, Wash., jury in his closing statements that there was no proof Bishop-McKean had tried to kill her husband, and that Brett Bishop could have hurt himself and blamed his wife. He also said that if she was responsible for the attack, the evidence suggested "a very half-hearted attempted" to kill, KOMO reported.

Jurors needed only three hours to reach the verdict, in which they also convicted Bishop-McKean, 44, of assault for the mallet and hatchet attack.

Bishop-McKean had maintained that an intruder broke into the home and tried to kill both her and her husband with the saw, but she had awoken and fought him off before her husband awoke. Police found no evidence to support that theory.

Bishop-McKean faces at least 15 years in prison at sentencing set for Oct. 4.
