AUGUSTA — State police say an autopsy has failed to determine how a hiker from Long Island, N.Y., died on the Appalachian Trail in Maine.

State police said today they’re investigating the case of 51-year-old Michael Guerette of Cherry Grove, N.Y., as an unexplained death for the time being. The Medical Examiner’s Office will conduct additional studies before reaching a determination on the cause of death.

Maine Public Safety Department spokesman Steve McCausland says Guerette had been hiking alone for two weeks on a portion of the Appalachian Trail in Maine.

Wardens initially said it appeared that Guerette fell and hit his head. His body was found Friday in Carrying Place Township in northern Franklin County.
