HARPSWELL — Cumberland County sheriff’s deputies and Maine Wardens helped rescue a Brunswick woman who became lost over the weekend while hiking with her teenage son in Harpswell.

The sheriff’s office was alerted to the problem at 9 p.m. Sunday. Theresa Desjardins, 45, had been hiking behind the Harpswell town office with her 15-year-old son when they became separated. He was able to find his way out and called for help.

Deputies deployed two canine teams and after an hour, the woman was found off the Cliff Trail, stranded on the shoreline on some rocks, according to a release from Sheriff Kevin Joyce. She was not hurt but dehydrated and scared.

The darkness and rising tide made it dangerous to use a technical rescue to get her back up to the trail or to use a boat, so the deputies helped her to hike out over the rocky shore, the release said. The entire rescue took about four hours, Joyce said.
