Sources say a deadly house fire on Staten Island was likely electrical in nature.
It broke out shortly before 11 p.m. at a home on Annandale Road in Arden Heights.
One neighbor says he couldn't believe how fast the fire spread.
"We saw the flame because somebody was walking the dog and they knock on my door. And then we went down stairs and started to sniff flame. We called 911 and before you know it that was it," he said.
After firefighters got the flames under control, they found 63-year-old Frances Quinones and her husband unconscious inside the house.
The victims were rushed to the hospital where Quinones was pronounced dead.
Her husband remains in serious condition.
