Utilizing a profile prepared by Scully, the FBI soon apprehends Eugene Victor Tooms. After passing a lie detector test, however, Tooms is released. Mulder knows it's a mistake. Once elongated, Tooms fingerpirnts match those at the crime scene. Events soon prove Mulder's theory as Tooms stretches himself to squeeze down a chimney and murder a fourth victim.
The next day, Mulder and Scully find a nestlike structure below Tooms last known residence. It is here that he hibrinates between killing sprees-substained by the stolen livers. In revenge, Tooms decides to make Scully his last victim, but-thankfully-Mulder arrives in time to stop him.
