AUGUSTA, Maine — The Maine Warden Service is seeking the public’s help in the effort to find a missing Tennessee woman.

Geraldine “Gerry” Anita Largay, 66, of Brentwood, Tenn., was hiking the Appalachian when she went missing on Sunday, Cpl. John MacDonald said in a news release issued Thursday.

Largay’s plan was to meet her husband on Monday in Wyman Township, an unorganized territory in Franklin County, MacDonald said. He said that Largay set a text to her husband at 7:15 a.m. but never arrived at their meeting place.

In an update issued shortly before 10 p.m. Thursday, MacDonald said that state game wardens are seeking “critical information” about a woman hiker who called an employee of the Stratton Motel in Stratton on Wednesday night reporting that she had spent Tuesday night with Largay at a lean-to on the trail. The name of the hiker, who said she was traveling south, remains unknown.

“The Maine Warden Service desperately needs to identify this hiker and wishes to speak to her about this incident,” MacDonald said. “Anyone with information who can help identify the hiker is asked to call the Public Safety Dispatch Center in Augusta at 800-452-4664.”

Earlier Thursday evening, MacDonald said game wardens would continue their search for Largay in what he described as high probability areas in the extremely large, heavily wooded section of the trail that runs through western Maine.

Largay is 5 feet 5 inches tall, weighs 115 pounds and has brown hair and brown eyes. She was last seen wearing a black pullover shirt, tan pants, a blue hat and a black and green backpack.
