FBI's investigation into the 1989murder of federal appeals Judge Robert Vance and subsequent bombings, which were ultimately linked to Walter Leroy Moody. The investigation revealed Moody's motive stemmed from a long-held resentment of the court system due to a prior bomb-related conviction and his contact with Judge Vance in a later case. The other bombs were intended to mislead investigators into believing the motive was racial hatred. The case highlights the importance of inter-agency cooperation (FBI, ATF, IRS, US Marshals, Georgia State Police, and US Postal Inspectors) and the meticulous collection and analysis of evidence in solving complex crimes.
