This file concerns Frank 'Lefty' Rosenthal, gambling-related investigations, and later allegations examined under the federal RICO statute. Miami records from 1970 renamed the matter from a Rosenthal-centered title to Multiple Sports News Service and document an interstate wagering investigation that used electronic surveillance; a 1971 report records federal gambling-related verdicts against several redacted defendants. The released material also includes interview material referring to Rosenthal and Las Vegas memoranda from 1978-1979 concerning an alleged plot involving Nevada political and media figures. Prosecutors sought grand jury testimony, but the Las Vegas office closed the RICO matter in September 1979 after completing its inquiry, subject to reopening if positive evidence emerged.
