Vincent Piersante was one of the early crusaders against the Detroit Mafia as a police detective in the 1950s, and he ultimately headed the organized crime squad for the Michigan Attorney General from the 1970s to 1985 when he retired as reported by Alan Stamm for Deadline Detroit.
In an era of corruption Piersante was known for his integrity. At his funeral service former Michigan Attorney General Frank J. Kelley said "he was a very dedicated policeman" as reported by Ken Palmer for the Lansing State Journal:
"He believed a policeman had a duty to serve, ferret out crime, protect a community and be a good person himself. He fit the definition of a hero policeman. He was a straight arrow."
Piersante was "a devout Roman Catholic," and "the importance of his Catholic Faith guided him in every facet of his life" as provided by his obituary.
