A 64-year-old woman and her 29-year-old daughter died when a fire broke out at their Long Island home overnight, and arson investigators are investigating the cause of the blaze, police said.
The woman's 26-year-old son escaped the burning Huntington Station home, possibly through a basement window, and was taken to the hospital with minor injuries, authorities said.
Reyna Parris and her daughter, Rosemarie Martinez, who relatives told investigators had Down syndrome, had been trapped inside the house, officials said.
A neighbor said he didn't see a lot of flames, but the house was consumed by smoke.
Police said the house was "extremely cluttered," making the investigation more difficult.
