Steven Avery is guilty  . . .  of falling in love.

The subject of the acclaimed documentary “Making a Murderer,” Avery reportedly dumped his fiancée of one week due to concerns that the woman might be a “gold digger,” The Wrap reported.

“Steve called me two times tonight and wants everyone to know that Lynn [Hartman] and him are done,” a friend of Avery’s, Sandra Greenman, wrote in a Facebook post to an Avery group. “She has been in this relationship for money and publicity. His eyes are finally opened!!!”

Avery’s niece, Carla Chase, posted her own Facebook message backing up Greenman’s post.

“So please, don’t let her be the victim as she’s trying to play,” Chase wrote.

The 54-year-old Avery popped the question to Hartman last week, People magazine reported. The couple had “dated” for eight months, mostly through letters and phone calls. Hartman finally met Avery in prison last week.

One of the reasons Greenman said Avery dumped his fiancee was because she was allegedly trying to profit off the relationship. Greenman cited a supposed $5,000 paid to Hartman to appear on the Dr. Phil show. The show released a clip on Sunday morning of Hartman trying to get in touch with Avery to no avail. A teaser article said Hartman would reveal her intended wedding dress during her appearances on Monday and Tuesday.

Chase said Hartman’s trouble getting in touch with Avery, however, is only spin.

“Lynn has actually blocked the prison [number] from her phone & Steven has not been able to get a hold of her,” Chase wrote on Facebook.

Hartman did not immediately reply to The Wrap’s request for comment.

Avery was charged in November 2005 with sexually assaulting and killing a woman. His then 16-year-old nephew, who lived on the same property Avery did, was also charged in the murder. Both men were convicted and sentenced to life in prison.

But Avery has always maintained his innocence. His conviction was overturned this year; however, prosecutors are appealing that decision.

Avery had previously been convicted of another rape, but was released from prison after 18 years when DNA tests showed he didn’t commit the crime. Two years later, he was locked up in the murder case.

The “Making a Murderer” documentary on Netflix brought Avery’s case to a wide audience and generated serious interest in his possible innocence. The show’s creators may produce a second season.
