Retirement of DuPage's chief investigator leads to shake-up in state's attorney's office
The recent retirement of Norm Hall, the former chief of investigations for the DuPage County state's attorney's office, has led to promotions and new hires within the office.
Officials announced Thursday that former Deputy Chief of Investigations Robert Guerrieri has been named chief of investigations. He will supervise nine investigators and support staff members responsible for all investigations of criminal offenses, service of subpoenas, summons, warrants and evidence preparation among other duties.
DuPage County State's Attorney Robert Berlin also announced the promotion of Special Investigator Dave Zdan to deputy chief of investigations and named former Naperville Police Department patrol watch commander John McAnally as the office's newest investigator.
Guerrieri joined the office in 2009 after 24 years with the Naperville Police Department. During the final three years there, he was commander of the special operations section where he supervised the department's intelligence and special enforcement units.
He also served as assistant commander of the DuPage County Major Crimes Task Force's intelligence unit, which provides assistance to local police departments during complex, multijurisdictional investigations in DuPage County.
"(Guerrieri) is fair, honest and compassionate, all important qualities to have when dealing with crime victims and their families," Berlin said. "He is also tough, determined and tenacious, traits that have enabled Bob to achieve success throughout his career."
Zdan, a retired longtime Wheaton detective, will take over Guerrieri's former position of deputy chief. In July 2013, he joined the state's attorney's office as a special investigator.
McAnally joined the office Monday, after a 26-year career as a Lisle and Naperville police officer.
"Both (Zdan) and (McAnally) are consummate professionals who have more than 60 combined years of service to the citizens of DuPage County under their belts," Berlin said. "I have complete confidence in their abilities to not only meet, but exceed the high standard of protecting the public and serving the victims of crime that DuPage County is known for."
