A Johnson County jury convicted an Olathe man Friday in the December killing of 54-year-old Susanne Goslin.
Stephen M. Collier, 60, of Olathe, was found guilty of second-degree murder.
Goslin lived with Collier and his wife, Molly Collier. Goslin helped care for Molly Collier, who suffered from a number of health issues.
Collier, who testified in his defense, said that the shooting was an accident that occurred as he attempted to disarm her.
He said she was holding a gun to her head and it went off when he tried to take the weapon from her.
Collier’s wife initially told police that after the shooting her husband told her he had shot Goslin. But on the witness stand, she denied having said that.
The doctor who conducted the autopsy testified that he did not detect the presence of powder residue on the victim that should have been there had she shot herself.
District Judge James Franklin Davis instructed the jury on first-degree murder, second-degree murder and involuntary manslaughter.
