Rhode Island police say twin 97-year-old sisters froze to death after falling down outside their home. He said the women were outside for 12 hours before the neighbor found them. They returned to Haley's home at approximately 8:30 p.m.
Police said Williams apparently fell when she was getting ready to leave her sister, Haley's, house on Friday night.
Nothing was missing from either of the sisters, or from the premises, leading investigators to think that no foul play was involved in their deaths.
In a statement from the Barrington Police, Chief John M. LaCross said, "On behalf of the men and women of the Barrington Police Department, our deepest sympathies and condolences are extended to the Haley and Williams' families during their tragic loss".
A neighbor discovered the twin sisters in critical condition the next morning.
Overnight temperatures in the area dropped as low as 11 degrees, with wind chills as low as minus 8. The Providence Journal reported that Haley lived at 21 Opechee Drive, Barrington, and Williams lived in East Providence.
"Ms Haley may have tripped on a rug on the floor of the garage as she attempted to enter her house to call for assistance".
It's highly improbable to find out which one of them fell first or if one of the women fell while trying to help the other one. An ambulance arrived to take the two elderly sisters to a Rhode Island Hospital. They were quickly pronounced dead.
On Friday night, much of New England recorded some of their winters coldest temperatures.
Jean Haley tried desperately to call for help after she noticed her sister, Martha Williams, had also fallen, Barrington Police told WHIO.
