"I don't know what's the problem, I have no idea, I don't know, I don't know," said Angela Brooks, the victim's sister.
When 42-year-old Dionne Bailey didn't come to the door for her daily carpool, her sister and brother-in-law pried open a bedroom window.
"It looked like she's sleeping. And I reached in, try to wake her and I found she was frozen. You know, stiff," described Brad Brooks, the victim's brother-in-law.
Dionne, and her daughters, 19-year-old Yanique, and 14-year-old sister Yolon, all shot to death, in their own beds.
Police found the body of 42-year-old Mark Bailey slumped over at the kitchen table.
They say he used a rifle to shoot his own wife and daughters, and then himself, after writing a note saying he was sorry.
"It's very difficult to comprehend how it is that someone reaches this point of despair," said District Attorney, Richard Brown.
Family members say the Bailey's had argued lately, over Mark's desire to have that rifle in the house.
Dionne actually moved out for three weeks in December.
But, neighbor Davison Joseph, who lives right downstairs, says it wasn't clear anything was wrong until Monday.
That's when he peered in the window and saw for himself.
"I just saw the lady lying here in the bed covered in blood," said Joseph.
The Bailey's were married for almost 20 years.
Mark drove a school bus in Nassau County.
Dionne worked as an assistant principal at Philip Randolph High School in Harlem, where one of her sisters also worked as a teacher, that's where they went to grieve.
