Pelham Fire Department officials told WMUR television station the birch tree broke about four feet from its base and hit the child. The boy went into cardiac arrest. He was taken to a Lowell, Mass., hospital, where he died.

Neighbors told the television station the boy was out trick-or-treating Saturday.

It was not immediately known what caused the tree to break.
