A Michigan man who bound and tortured his wife, then killed his two young children and two teen stepchildren has pleaded guilty, reports CBS Detroit.
Gregory Green, who spent 16 years in prison for killing his pregnant first wife, admitted to the September 2016 slayings after being ruled competent to stand trial.
Green’s biological children, 5-year-old Koi Green and 4-year-old Kaleigh Green, died from carbon monoxide poisoning. Authorities say Green left them in a car with the engine running.
His stepchildren, Chadney Allen, 19, and Kara Allen, 17, were fatally shot in front of their mother, Faith Green.
Faith Green was slashed across the face with a box cutter, shot in the foot and tied up, but survived.
According to prosecutors, Green called 911 early morning on Sept. 28 and admitted to killing his family. When police arrived, he was waiting on the porch and immediately taken into custody, according to CBS Detroit.
Sentencing for Gregory Green is scheduled for March 1. He will serve two mandatory years, followed by 45 to 100 years in prison. He will be 97 before being eligible for parole, according to prosecutors.
A judge rejected a personal protection order for Faith Green in 2013. She had also previously filed for divorce.
Gregory Green and Faith Green married two years after he left prison on his fifth request for parole.
