I am originally from Detroit and I knew the Licavolis. If you are not aware, Peter was a prominent Don in the Detroit Mafia, his brother Yonnie had spent many years in prison having been convicted of murder. Peter lived on Balfour st. in Grosse Pte. Mich. They owned a ranch in Tucson, Arizona where they eventually moved to. Peter Licavoli is deceased and so is Yonnie of course. Peters son Michael recently passed away in Tucson from what I hear was a heart attack. There are two other sons, Teddy and Peter and a daughter Cathy. Peter Sr. had a sister who was married to Long Joe Bommarito. You can go to www.ancestry.com
and search the Licavoli name to determine the date of Peter's death. His brother Dominick Licavoli was a real estate broker and as far as I know he is still alive and living in Michigan. Hope this helps you.
