Retired police dog makes an interesting discovery with the help of its owner

Terrible find 

Kyle and John arrived at the tree. The agent pulled the loose bark back a bit further to get a better look at what was hidden inside the tree. Then he saw it. John’s heartbeat sped up. Even after all these years he was still shocked by finds like this. It was even worse than Mr. Smith had told. 

Somehow someone had managed to put an entire human skeleton in the tree. It was only thanks to Kyle’s training and amazing senses that the remains had even been found. The skeleton was hidden so well that the entire tree would need to be cut down before they could even begin researching. The Smiths never could have imagined that their new pet would come across such terrible things.
