Bill Patterson

Bill Patterson was the FBI's chief profiler, and 's former mentor. He worked for three years investigating a series of grisly murders that culminated in the arrest of John Mostow, a Soviet emigrant. When the murders continued after Mostow's arrest, he requested that assign Mulder to the case.
Mulder found Patterson's partner, Agent Nemhauser's dismembered body in Mostow's sculpture studio. Mulder confronted Patterson and accused him of continuing the murders. Patterson attacked Mulder and fled the scene, only to be slashed with a razor blade by Mulder and fall off the rooftop. He recovered and was imprisoned, claiming "It wasn't me!" (which could mean he was possessed).
Bill Patterson was played by Kurtwood Smith.
