RAYMOND, N.H. — Police in New Hampshire say a man who tried to dig around a 6,000-pound boulder in his yard became pinned under the rock and died.

Police said 47-year-old Paul Comeau Jr. had been working on extricating the boulder over several months in his yard in Raymond. He was digging around the rock in an attempt to free it. While he was working on it Monday, the boulder became dislodged, causing him to be pinned between it and the wall of a ditch.

First-responders discovered Comeau was not conscious and was not breathing. A tow truck was needed to lift the boulder off him. He was pronounced dead at the scene.
