Police say a man apparently asphyxiated his two young children using exhaust from a car, fatally shot his wife's two older children and shot and slashed his wife at a suburban Detroit home.
Dearborn Heights police Lt. Michael Krause tells The Associated Press that officers responded after getting a 911 call from the man early Wednesday indicating that he'd killed his family.
Krause says officers found the man on the porch and took him into custody.
Krause says police found the man's children, a 4-year-old girl and a 6-year-old girl, on the first floor of the home.
In the basement, he says they found the bodies of a 17-year-old girl and a 19-year-old man along with their mother, who had gunshot and knife wounds.
Krause says the woman is in critical condition.
