Police said Green called 911 early Wednesday and confessed to the killings. Green was arrested when officers arrived.
A MI man has been arrested for killing his four children and leaving his wife seriously injured on Wednesday morning, police said. Police say when they arrived, they found him waiting on the front porch for the officers and he was taken into custody, WXYZ reported. The woman was transported to Oakwood Hospital in critical condition, Krause said.
After the arrest, police went into the home and discovered Green's 39-year-old wife, Faith, in the basement of the home, bound with duct tape and zip ties.
The suspect is expected to be arraigned Thursday. Police believe the suspect moved the youngest children from the auto into the home as they succumbed to the carbon monoxide and placed them in their beds, reports CBS Detroit. But local media identified the suspect as Green, the father of the youngest victims, and said the injured woman was Faith Green, who was the mother of all four. Two younger children - a girl, 4, and boy, 6 - died from carbon monoxide poisoning in a auto with a modified tail pipe, police said. After they died, he moved their bodies back into the home and placed them in their beds. Investigators say both teens were shot multiple times, execution style, and were pronounced dead at the scene.
Green served 15 years in prison for the murder of his first wife, who was pregnant, when Green stabbed in their Detroit home in 1991.
A father accused of killing four siblings Wednesday was convicted in 1992 of murdering his pregnant wife, according to MI records.
The Greens married in 2010, two years after Gregory Green left prison on his fifth request for parole. He then completed several cognitive programs and was parole in 2008.
Police say they had been to the family's house several times in the past for domestic violence and family run-ins.
Krause said "some sort of domestic dispute" preceded the killings. "We do have the suspected offender in custody so there is no concern for the neighbors".
"I don't need bond", Green told the judge. Jeff says the couple argued and then he heard a gunshot.
"I just figured they were a regular family", he said. "I mean, I don't think I deserve it".
The family recently had a birthday party at the home for the youngest child.
The circumstances of the crime scenes in 1991 and Wednesday are morbidly similar.
They were said to be a normal family, quiet and hardworking. All the relatives were here. They would have parties, and they just had two or three picnic things this summer. "I came outside and that's when I found out what happened". "He seemed like a very good guy".
