A proud U.S. Navy veteran, Mr. Potempa served as a police officer in Skokie and Rosemont, and as police chief in Bloomingdale. His passion for investigation led him to open his own firm, PPI: Potempa Private Investigations.
  
Mr. Potempa was involved with many fraternal and political organizations, including the DuPage County Chiefs of Police Association; the Illinois Association of Chiefs of Police; ASIS International, the world’s largest association for security management professionals; the American Legion; the Bloomingdale Township Republican Party; and the DuPage County Republican Party.
 
Mr. Potempa also was a past commander of the Alvin W. Koehn 5813 VFW, and of the Bloomingdale Township Republican Party. For many years, he was president of the homeowners association at his Bloomingdale subdivision.
 
In addition to Sandi Potempa, Mr. Potempa is survived by a son, Michael Fracaro. Donations appreciated to The Hundred Club of DuPage County.
