Steven Avery has broken off his engagement to Lynn Hartman after less than a month. 

Avery surprised many of his supporters in September when it was announced that he had gotten engaged to Lynn Hartman, a legal secretary working on his case, just a week after meeting her in person. The two had been in correspondence over the phone and via email for several months beforehand.

The engagement was announced on the Steven Avery Project Facebook Page. 

However it seems that Avery's feelings have changed towards Hartman after she appeared on Dr. Phil to discuss their relationship. The Making a Murderer subject apparently cut off all communication with Hartman after the episode aired and has since sent her a letter from his lawyer, Kathleen Zellner, informing her that their relationship is finished. 

The letter, which can be viewed over on InTouch, not only served to inform Hartman that her relationship with Avery is finished but also warn her that legal action could be pursued if she continues to discuss her relationship with Avery in public. 

Here's the letter in full: 

Dear Ms. Hartman,

I am writing you at the request of my client Steven Avery. Please let this letter act as formal notice that Mr. Avery terminated his engagement with you effective yesterday, October 2.

As Mr. Avery expressed to you during your relationship with him, he deems his correspondence and communications with you to be confidential. This constitutes an oral agreement with him. You should therefore cease and desist giving interviews of any kind concerning your relationship with him. Aditionally, you should refrain from selling distributing, or otherwise disseminating any letters from, or the substance of any other communications with Mr. Avery. You should also not sell, distribute, or otherwise disseminate any photographs taken of you and Mr. Avery, and you should refrain from otherwise trying to profit from Mr. Avery’s likeness or your relationship with him. Finally, you should not offer any opinions regarding Mr. Avery’s case, or his guilt or innocence.

Although we believe that you have already breached the oral contract, we will not take any legal action against you unless you continue to violate the terms of your agreement with him.

I appreciate your cooperation in these matters.

Sincerely,

Kathllen T. Zellner
