The twins had gone out to dinner the night before with their 89-year-old younger sister, police said. All three went to Haley’s Opechee Drive home at about 8:30 p.m.

The bodies of Jean Haley and Martha Williams were discovered at 21 Opechee Drive at about 8:11 a.m., local police said.

Twin sisters who were 97 years old were found dead early Saturday at a Barrington, R.I. home after authorities believe they both accidentally tripped and fell during an extremely cold night.

Later that night, the younger sister left, and authorities believe Williams may have tripped and fallen in the driveway as she walked out to her car. Investigators believe Haley was walking through the garage to go inside and call for help when she tripped on a rug and fell, police said.


Investigators do not suspect criminal activity in the deaths.

Though cold temperatures are believed to have played a role, the cause of death has not been determined, police said.

Barrington Police Chief John M. LaCross offered his condolences to the victims’ families Sunday.

“One 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,” LaCross said in a statement.
