Steven Avery and his new fiancée Lynn Hartman will appear on a special two-part episode of Dr. Phil, airing Monday and Tuesday.

It’ll be Avery’s first television interview since Netflix’s Making a Murderer thrusted him into the spotlight. The 54-year-old convict is currently behind bars for the 2005 murder of 25-year-old Wisconsin photographer Teresa Halbach – though he has maintained his innocence.

He’ll call into the show from Wisconsin’s Waupun Correctional Institute, where he’s lived for the past 11 years. According to a preview for the special, the call was a surprise to Hartman.

As she had done with PEOPLE, Hartman shares their love story on the show – even giving viewers a sneak peek into her wedding dress.

Making a Murder cast doubt on Avery’s conviction, advancing the theory that he might have been framed in retaliation for filing a $36 million lawsuit against Manitowoc County and authorities after a wrongful conviction for rape sent him to prison for 18 years before being overturned.

Hartman watched the 10-part Netflix series and came to believe Avery was innocent, she told PEOPLE. She wrote him a letter of support and sent a handful of photos, offering “any kind of support I could in any way that I could,” she said.

“As it turned out, he became a support system for me,” she told PEOPLE. “here I am talking to a man convicted of murder, and he was my support system. But that’s what I fell in love with. This man still had the love in his heart to reach out to people and write them with support.”

Avery’s nephew Brendan Dassey was also convicted in Halbach’s murder. Dassey recently had his conviction overturned. Wisconsin’s attorney general filed an appeal in early September overturning the judge’s decision.

Avery, who switched his lawyer to Kathleen Zellner, who specializes in wrongful convictions, told Dr. Phil, “The truth is coming out and sooner or later, all the truth will come out.”
