But this was not the first time Gregory Green had committed such a heinous act. It was the second time he had killed his own family. In this article, we will delve into the disturbing story of Gregory Green and the events that led to his unimaginable actions.

Who Was Gregory Green?

Gregory Green was born on 10 December 1966, in Detroit, Michigan. He grew up in a troubled household, with his father being abusive towards his mother. As a result, Green and his siblings were often subjected to physical and emotional abuse.

Despite his difficult upbringing, Green was a bright student and excelled in school. He went on to attend the University of Michigan, where he earned a degree in engineering. After graduation, he worked as an engineer for several companies before starting his own business.

Green was known to be a devoted husband and father. He married his high school sweetheart, Faith Harris, and together they had two children, Koi and Kaleigh. However, their marriage was not without its problems. Green had a history of domestic violence and had been arrested for assaulting Faith in the past.

The First Murder

In 1991, Green’s marriage to Faith was falling apart. He had become increasingly violent towards her, and she had filed for divorce. On November 1, 1991, Green went to Faith’s home and shot her in the head, killing her instantly. He then turned the gun on himself in a failed suicide attempt.

Green was arrested and charged with first-degree murder. However, he was found not guilty because of insanity and was sent to a psychiatric hospital for treatment. After just four years, he was released and deemed fit to re-enter society.

The Second Murder

After his release, Green moved to California and started a new life. He remarried and had two more children, Chadney and Kara. However, in 2009, his second marriage also ended in divorce, and he moved back to Michigan with his two children.

In 2010, Green reconnected with Faith, and they eventually remarried. They also had two more children, Koi and Kaleigh, bringing their total number of children to six.

However, Green’s violent tendencies resurfaced, and he and Faith’s relationship became increasingly volatile. In 2013, Faith filed for divorce, citing Green’s abusive behavior.

The Tragic Events of September 21, 2016

On the morning of September 21, 2016, Green called 911 and calmly confessed to the murder of his four children, Koi, Kaleigh, Chadney, and Kara. He also admitted to attempting to kill Faith by poisoning her with carbon monoxide.

When the police arrived at the scene, they found the four children dead in their beds. Faith was found unconscious but alive in the basement, where Green had left her with a generator running to fill the room with carbon monoxide.

Green was arrested and charged with four counts of first-degree murder and one count of attempted murder. He pleaded guilty to all charges and was sentenced to life in prison without the possibility of parole.

The Aftermath

The community of Dearborn Heights was left reeling from the tragic events of September 21, 2016. The loss of four innocent children was devastating, and the fact that their own father was responsible made it even more difficult to comprehend.

The case also sparked a debate about the justice system and how it handles cases of domestic violence. Many questioned how Green was able to be released from a psychiatric hospital after just four years, despite his history of violence.

The Documentary

In 2019, a documentary titled “The Man Who Killed His Family Twice” was released, shedding light on the events leading up to the tragic murders. The documentary features interviews with family members, friends, and experts, providing insight into Green’s troubled past and the warning signs that were missed.

The documentary also delves into the failures of the justice system and how Green was able to slip through the cracks and commit such a heinous act for the second time.


The story of Gregory Green is a tragic and disturbing one. It highlights the devastating effects of domestic violence and the failures of the justice system to protect victims and hold perpetrators accountable.

The loss of four innocent lives is a tragedy that will never be forgotten, and the community of Dearborn Heights will continue to mourn the loss of Koi, Kaleigh, Chadney, and Kara. May their memory serve as a reminder to always speak out against domestic violence and to never ignore the warning signs.
