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

Backup is on the way 

As Mr. Smith withdrew from the tree, Kyle stayed fixated on the scene with intense focus. He seemed to be waiting for his next instruction. But the Smiths had no idea how to handle the situation. This was above them. They needed the help of real experts, people who knew Kyle very well.

Mr. Smith decided to call John once more. With his voice shaking, he told John what they had discovered in the old oak. John immediately sent in a police forensics team and told Smith that he and his family needed to get back immediately. Backup was on its way.
