Louise Chaput, a 52-year-old Canadian psychologist, was last seen November 15, 2001, when she arrived at the Appalachian Mountain Club’s Pinkham Notch Lodge for a solo hiking trip in the White Mountains. She asked for a short hike recommendation, then headed toward the Lost Pond Trail. Chaput was reported missing after she did not return home as expected on November 20, 2001.

Her car was found parked at the Direttissima Trailhead near the Lost Pond Trail, but her body was discovered days later on November 22, 2001, near Glen Ellis Falls. She had been stabbed multiple times; the death was ruled a homicide. Chaput’s vehicle remained at the trailhead and appeared untouched, though her car keys and some belongings were missing. No suspects have been identified and investigators have described the killing as apparently random.

Does anyone have information about hikers or strangers seen on the Lost Pond or Direttissima trails around November 15–22, 2001?
