Patty Kearney was watching TV with her husband around 9:30 on Monday night when he got up to investigate a loud crash on the back porch.
The 63-year-old, who has COPD and lung cancer, saw her husband backing out of the room with his hands in the air.
A man wearing a hockey mask began threatening the Kearneys with a wrench and demanding money. Unfortunately for him, Kearney figured out that he didn't have a gun and went after him with a backscratcher.
"I said not in my house, not in my house, and I boom, boom, boom," Kearney told FOX 59. "I just hit him in the head, hit him in the head, hit him until he got right there."
When the man dropped the wrench, Kearney picked it up and hit him with that too until he ran out the door.
"If he hadn't have got out that back door, I'd have beat him to death. And I know I would've because I was that mad at that person in my house for doing this to me," she said.
Marion Police are still trying to identify a suspect.
