In September 2016 in Dearborn Heights, Michigan, 19-year-old Chadney Allen was shot and killed in his family’s home by his stepfather, Gregory Green. The attack also killed Chadney’s 17-year-old sister, Kara Allen, and their two younger half-sisters, 5-year-old Koi Green and 4-year-old Kaleigh Green.

He then forced her to watch as Chadney and Kara were taken to the basement and shot execution-style with multiple gunshot wounds. After killing the teenagers, Green is said to have poisoned Koi and Kaleigh with carbon monoxide from a car in the garage, then moved their bodies back into the house and placed them in their beds. He called 911 in the early morning, confessed, and waited on the porch to be arrested.

Reports state the killings followed marital strife after Faith Green filed for divorce; Green had a prior conviction for a 1991 murder for which he served 16 years before being paroled in 2008. He was charged with multiple counts including first-degree murder, torture and assault; after being found competent he pleaded guilty to four counts of second-degree murder plus torture and assault and received 45 to 100 years in March 2017.

Did anyone in Dearborn Heights know Chadney or the family and have recollections that could shed light on the period leading up to September 2016?
