DEARBORN HEIGHTS, Mich. » A Detroit-area man who served 16 years in prison for killing his first wife was charged today with killing his two children and two stepchildren, and torturing his wife.

Prosecutors allege that Gregory V. Green bound his wife, cut her face with a box cutter and shot her in the foot, before fatally shooting her teen children in front of her Wednesday at the family’s home in Dearborn Heights.

Green, 49, also is accused of killing his and his wife’s young daughters by carbon monoxide poisoning at the home.

He’s charged with first-degree murder, assault, torture and other crimes. Green heard the charges during a brief court hearing today and was returned to jail without bond. He wasn’t accompanied by a lawyer.

“I don’t need bond,” he told Judge David Turfe. “I mean, I don’t think I deserve it.”

Police said Green called 911 early Wednesday and confessed to the killings. His wife, Faith Green, had recently filed for divorce. She survived her injuries.

“The alleged evidence in this case will show an appalling level of domestic violence that ?was cataclysmic,” prosecutor Kym Worthy said in a written statement. “We must push the issue of domestic violence back to the forefront and be constantly educated about it.”

Faith Green cited a “breakdown in the marriage relationship” in her divorce filing. She also filed for divorce in 2013 but the case was dismissed for lack of action. A judge rejected a personal protection order that same year.

The Greens married in 2010, two years after Gregory Green left prison on his fifth request for parole. He pleaded no contest to killing his first wife, who was pregnant, in 1991.

The victims were Koi Green, 5, Kaleigh Green, 4, Chadney Allen, 19, and Kara Allen, 17.
