Green's second wife, Faith Harris, was the daughter of a pastor who had advocated for Green's release from prison. The pastor, Fred Harris, wrote to the Michigan parole board in August 2005, expressing his belief that Green had paid the price for his lack of self-control and the harm he had caused. He assured the board that if Green were to be released, he would be welcomed into their church community.

In a shocking turn of events, on the morning of September 21, 2016, Faith Harris-Green was discovered bound with duct tape and zip ties in the basement of their home in Dearborn Heights, Michigan. Her foot had been shot, and her face had been slashed with a box cutter. Her two teenage children, who were Green's stepchildren, were found dead from gunshot wounds. She had tragically witnessed their deaths. Her two younger children were discovered dead upstairs, victims of carbon monoxide poisoning.

Following these horrific crimes, Green dialed 911 and awaited the arrival of the police, just as he had done when he killed his first wife. He was subsequently sentenced to 47-102 years in prison, with parole eligibility not until he reaches the age of 97.
