Officials are investigating the death of a 92-year-old woman in Oak Bluffs after her body was found outside her home on Munroe avenue Saturday.

The woman, who was not identified by police, was found on a walkway leading to the home’s front door by a family member who lived nearby and had been unable to reach her, state police wrote in a statement. Police were alerted to the incident at about 2 p.m. Saturday and they believe the woman had been outside in the extreme cold for an unknown period of time, possibly overnight.

Frigid temperatures hit the Island Friday night into Saturday, dipping below zero. Harsh winds made it feel like minus 20.

The Office of the Chief Medical Examiner will conduct a post-mortem examination on the woman.

Oak Bluffs fire Deputy Chief Stephen Foster declined to comment on the death, referring questions to state police.
