STOCKTON SPRINGS — A World War I soldier whose only living relative was from Maine has been laid to rest with full military honors.

Army Pvt. Thomas D. Costello of New York died of shrapnel wounds and was buried along with two other soldiers in a wooded area in northern France in 1918.

An investigation was launched in 2006 after French nationals found human remains and World War I artifacts. Costello was recently identified using dental records.

Military officials tracked down Michael Frisbie of Stockton Springs, who is Costello’s only surviving relative. Frisbie attended today’s service at Arlington National Cemetery.
