Task: Question Answering
Input (English): Passage: In the forest near the small isolated town of Maiden Woods a team of loggers goes inexplicably missing. Unable to contact them the Foreman goes searching for them, finding only a logger's severed arm. He is then violently killed in his truck by an unseen creature.
Later in town Sheriff Paul Shields and his new deputy Donny Saunders from New York speak to farmer Ron who insists one of his valuable horses has been stolen, though without evidence of theft it is assumed the horse merely escaped through an open gate. Paul then leaves to pick up his son Adam from his wife Susan who no longer lives with him after the accidental death of their other son, Tim. That night Adam sees a creature in the back yard and when Paul investigates he hears but does not see a large creature in the trees.
The next morning Paul finds large footprints in the snow around his house that appear to come from an animal with hooves that walks on two legs. Donny informs him the footprints are around everybody's houses in the entire town. Paul and Donny follow the footprints into the woods where they also find large claw marks on the trees where the footprints disappear. After hearing from Park rangers that no known animal with hooves could walk such a distance on two legs Paul assumes the whole thing is a prank. Paul later hears from the town priest that his dog and a lot of other animals have gone missing. Paul then goes to a local store where Ron's daughter Clair and several hunters confront him with their fears about old Indian stories of creatures living in the woods, though Paul dismisses this. Earl, another hunter informs Paul that even though it is hunting season all the deer and other forest animals have all disappeared, meaning a large new predator may be in the area. 
Question: What are the first names of Tim's parents?
Output (English): Paul.
