Joseph Sullivan (FBI): Joseph Aloysius Sullivan (February 17, 1917 – August 2, 2002) was a Major Case Inspector for the Federal Bureau of Investigation.  Born in Montreal, Wisconsin, he grew up in Hurley, Wisconsin.  He was involved in a number of highly publicized cases in the sixties and seventies including the assassination of Martin Luther King Jr., the murder of United Mine Workers reformer Joseph "Jock" Yablonski, the Sterling Hall bombing at the University of Wisconsin–Madison, and the Kent State shootings.  Despite his involvement in such high-profile cases, Sullivan is best known for his relentless search to track down the killers of three civil rights workers, who were brutally slain in Mississippi in 1964.  The character played by Willem Dafoe in the movie "Mississippi Burning" is loosely based on Sullivan.  According to "The FBI - A Comprehensive Referecie Guide" (1998), edited by Athan G. Theoharis, Sullivan was also the model for Inspector Lew Erskine, the lead character played by Efrem Zimbalist, Jr., on the TV series "The FBI".
