Did you check the crown of the tree? Maples are known for getting water inside from a broken main branch and rotting from the inside out. I've had a couple do that. One was three feet across and 60 feet up to the first branch - magnificent looking tree. It came down in a big wind and looked just like that inside. The dark wood was soft near the base and spongy nearer the top.
