The blood was from the man named Steve.
As for the dog blood, it should be from the dog that belonged to the kids from the town down the mountain.
Luke didn't enter the cabin. Instead, he quickly tracked Steve's blood into the woods.
Janet and Annie's scents were mixed in with the smell of Steve's blood.
Annie had called Luke probably because the couple had asked for her help.
When he spoke with Annie, Luke had mentioned that he was a police officer and the safety instructor for No. 37 Middle School's campsite.
If she called 911, it would take forever for the police officers to arrive.
This wasn't a town, but the woods in a mountain, and the police officers had every reason to be wary of accidents.
Luke moved quite fast. He covered several hundred meters quickly and stopped in front of a dilapidated cabin near a pool.
He approached the cabin and whispered, "Annie, don't make a sound. It's Luke."
