The home at 145-50 230th Place in Cambria Heights was a house of horrors when police discovered the four dead bodies.
A despondent Queens man apparently killed his wife, teenage daughters and himself with a rifle, leaving a suicide note on a livingroom table, police said.
Cops believe the murder-suicide happened Sunday night but authorities didn't receive a call about it until about 7 a.m. Monday morning, when the man's sister-in-law could not reach her sister, his wife.
When police arrived, they found the man, Mark Bailey, dead with a gunshot wound in the family's living room in Cambria Heights. His 42-year-old wife, Dionne, and their 19- and 14-year-old daughters, Yonique and Yolon, were found in their bedrooms.
Police say a note found near his body read: 'I am sorry.' Police say it was signed by the father.
Officials said the man used a "high-powered" 9-millimeter assault rifle.
"It is very difficult to comprehend how it is that someone reaches the point of despair that they would commit an act such as this," said Queens District Attorney Richard Brown, who gave a press conference at the grisly scene.
Dionne Coy-Bailey had been an assistant principal at A. Philip Randolph Campus High School in Harlem for two years. Co-workers there left them in "disbelief and denial."
Sources say there is no history of domestic violence and there's no known explanation for his burst of violence.
