Peter Joseph Licavoli (June 7, 1902-January 11, 1984) was an organized crime figure in St. Louis and, with his brother Thomas "Yonnie" Licavoli and cousin James Licavoli, he worked with Jewish gangsters to take over illegal gambling in St. Louis. Due to legal and gang-related problems, the Licavolis soon moved on to Detroit, Michigan and would control criminal operations in Detroit and Toledo, Ohio, throughout the Prohibition era. Wikipedia
Unfortunately for Mr and Mrs Licavoli, Peter Joseph nor his younger brothers Thomas and Dominic ever showed much interest in living anything but a fast and dangerous life of crime and rascality. www.geocities.com/jiggs2000_us/licavolip.html
