Police said the man was on a ladder, pruning a tree with a chain saw, when a man helping him said he thought the branch being cut was going to fall.

The man with the chain saw, identified only as a resident of the home, started down the ladder but still was at least three feet off the ground when the branch fell, striking him, police said. The force of the impact knocked the man off the ladder and to the ground, causing the injuries, police said. Police said when emergency responders arrived the man was "conscious and responsive."
