Stardust. A nine-story hotel addition was completed in 1964. A year later, the Stardust was purchased by Lodestar, Inc., which consisted of major Desert Inn stockholders such as Moe Dalitz, who had affiliations with organized crime. By the end of 1967, there were reports that Howard Hughes made a deal to purchase the Stardust for $40 million, although the agreement later fell apart. Negotiations were underway again in March 1968, despite monopoly concerns; Hughes already owned several other Las Vegas casinos. Hughes received preliminary approval from the Nevada Gaming Control Board, which stated that his purchase would not give him a monopoly on Las Vegas gaming. However, a federal antitrust investigation was launched days before the purchase would have been finalized. Hughes eventually dropped his purchase plans in August 1968. Nevada governor Paul Laxalt criticized the investigation and denied that Hughes' purchase would have constituted a monopoly. In 1969, Parvin-Dohrmann Corporation purchased the Stardust from Lodestar for nearly $40 million. Parvin-Dohrmann, based in Los Angeles, also operated the Fremont and Aladdin resorts in Las Vegas. Parvin-Dohrmann was renamed as Recrion Corporation in 1970, and Al Sachs was chosen as the new general manager for the Stardust, after serving as the casino manager there. During 1970, NASA loaned a moon rock to the Stardust for display in the resort. A fire broke out at the Stardust two weeks later. The moon rock was secured, and 500 people were evacuated. A fireman was killed, and several guests had to be treated for smoke inhalation. Arson was ruled out as the cause of the fire, which began in a first-floor supply room full of flammable cleaning fluids. In 1972, hotel company Hyatt began negotiations to purchase Recrion and its properties. However, Recrion soon canceled plans to sell the Stardust. Allen Glick, a San Diego developer, purchased the Stardust in 1974, using money borrowed from the Teamsters Union Pension Fund. Glick made the purchase through his company, Argent Corporation. In 1975, concerns were raised that Argent executive Frank Rosenthal was involved in the company's casino operations, despite not being licensed. In May 1976, the Nevada Gaming Control Board launched an investigation into a slot cheating operation at the Stardust, possibly dating back to 1968. Dozens of former and current employees were questioned as the board sought to determine their involvement in the operation. The investigation soon widened to look at Argent's other casino properties,
