On September 21, 2016, four-year-old Kaleigh Green was one of four children killed in a violent attack inside a Dearborn Heights, Michigan, home. Kaleigh and her five-year-old sister, Koi Green, died of carbon monoxide poisoning after a plastic tube was attached to a car muffler and run into the house. Two older children, Chadney Allen, 19, and Kara Allen, 17, were shot and killed in the basement.

Their father, Gregory Green, also attacked the children’s mother, Faith Harris-Green: she was bound, slashed with a box cutter, shot in the foot, forced to witness the killings of the older children, and survived. Gregory Green called police, waited on the porch, and was taken into custody without incident. He had a prior conviction for the 1991 murder of his first wife and had been paroled in 2008.

Gregory Green was charged with multiple counts including first-degree murder, torture, and assault with intent to do great bodily harm. In February 2017 he pleaded guilty to second-degree murder, torture, and assault and received a sentence of 47 to 102 years in prison. Does anyone have information about the victims or that evening that could help fill gaps in the timeline?
