Bobby Delaughter was a prosecutor and judge in Mississippi in the late 20th century. He is similar to Atticus Finch in that they were both lawyers with famous cases, although Atticus was the defense attorney and Delaughter was the prosecutor.
Like Atticus, Delaughter was a famous attorney. Each of them was famous for one case.
DeLaughter is best known for leading the state's successful prosecution of Byron De La Beckwith for the assassination of civil rights leader Medgar Evers in 1994, more than 30 years after the crime. (wikipedia)
Atticus commented that the Robinson case was significant in his career.
Scout, simply by the nature of the work, every lawyer gets at least one case in his lifetime that affects him personally. (ch 9)
Of course, Delaughter might not have been as ethical as Atticus, since he was convicted of bribery. Each character also had a movie mad about him. Of course, Delaughter was a real person and Atticus was fictional.
