What Fresh Hell? (2006)

The team hears that eleven year-old Billie Copeland is abducted from the playground where her mother coached. This occurred sometime after a man was seen around with a leash, asking for help to search for his dog Candy. First the teams suspects her only six months divorced, father William, who turns up nearly 24 hours later with his cell phone turned off. He was discretely in oncology, for terminal lymph cancer, and single-handedly attacks a local Internet-filed sex offender, but that man never attacked children. A girls body is dragged from the river, but this is an unrelated event. Then a neighbor reports Donald Curtis, same age, car, even a recently deceased Labrador named Candy and extensive porn, but no trace of Billie.
