The headstone tells of murder by poisoned oyster.
The original headstone is in the Pelham Historical Society's headquarters.
Cache container is a match tube inside a small pill bottle to help keep it dry.
The theme of the cache is the headstone of Warren Gibbs. The headstone coordinates are N 42 21.154 W 72 24.340, as you face the cemetery its in the right front corner, the only white one.
Thanks to ClanDelaney and cool camaro for replacing cache.
You just have to move 2 small stones from in front of the container.
Hidden by wide glide and adopted in his memory
