When Lynn Hartman appeared on Dr. Phil, she gushed over her relationship with convicted murderer Steven Avery.

“Within the first month, he was telling me that he knew he wanted me to be his wife,” Hartman said. “I was excited. He had singled me out. It made me feel special. He told me I was beautiful.”

Hartman reached out to Avery after watching Making a Murderer, a Netflix documentary series that tells the story of Avery’s conviction for murdering a 25-year-old woman in 2005. Avery proclaims his innocence to this day, and his legal team suggested that the Manitowoc County, Wisconsin police department may have planted evidence and framed Avery for murder because he brought a $36 million lawsuit against them for false imprisonment in a rape case years earlier. Hartman says she wrote a letter to Avery and he responded quickly. Shortly thereafter, Hartman went to visit Avery behind bars.
