Yvonne Stern initially filed for divorce after learning of her husband's infidelity, but took him back. She has said she does not believe he was responsible for the attempts on her life.
She told ABC News that the sloppiness of the attempts to murder her made her confident that her husband could not have been involved.
"Is this the plot of a mastermind? My husband is brilliant. He's smart. He's talented. He would never be capable of doing such a terrible job," she said.
