A Missouri woman admitted Monday to plotting with her church pastor, who was also her lover, to murder her husband, Fox 4 reports.

40-year-old Teresa Stone pled guilty to conspiracy to commit murder in the March 2010 shooting death of her husband Randy Stone.

Teresa Stone confessed that she and her 51-year-old church pastor David Love agreed one of them would kill Randy Stone. Randy Stone was later found shot to death in his office at an insurance company.

David Love admitted shooting Randy Stone to death in November 2011, and pled guilty to second-degree murder and armed criminal action. He is serving a life sentence.

Love's attorney admitted at the time that it was well known Love and Teresa Stone were having an affair. Randy Stone's relatives told Fox 4 they believe the affair lasted for as many as ten years.

Love once was the pastor of New Hope Baptist Church in Independence, and delivered part of Randy Stone's eulogy. He moved to South Carolina not long after the murder and was arrested there in November 2010.

Teresa's Stone's guilty plea ensures she will not serve more than 10 years in prison. She will be sentenced in June, and remains free on bond.

Her husband's relatives say they are outraged over what they see as a lenient sentence for a heinous crime.

“I think she should have got a lot more time than 10 years,” Randy Stone's cousin John Stone told Fox 4. “I got 16 years for stealing cars and this woman takes my cousin’s life, a Christian, a good man, and 10 years? I just don’t understand the law.”
