Gentile, a Las Vegas criminal defense attorney, represented Grady Sanders, the owner of Western Vault Corporation. On January 31, 1987, undercover police officers with the Las Vegas Metropolitan Police Department reported that four kilograms of cocaine and almost $300,000 in travelers' checks were missing from a safety deposit vault at Western Vault. The items had been used as part of an undercover operation conducted by Metro's Intelligence Bureau. Sheriff John Moran held a press conference on February 2, 1987, naming the police and Western Vault employees as suspects.
Over the following year, press reports indicated that investigators focused on Sanders and Western Vault rather than the two police officers who enjoyed free access to the vault. Reports described other customers claiming missing items, Western Vault suffering heavy losses and going out of business, police officers being cleared after passing lie detector tests administered by Ray Slaughter, and Sanders refusing a police polygraph. One report noted that $264,900 in currency had been seized from an unrented box at Western Vault.
Hours after Sanders was indicted, Gentile held a press conference on February 5, 1988. He stated that the evidence would prove Sanders innocent, that Detective Steve Scholl was the person most likely to have stolen the drugs and checks, and that four of the other alleged victims were known drug dealers and convicted money launderers who had been pressured by police after getting into trouble themselves. Gentile had researched Rule 177 the evening before with two colleagues and concluded that the timing six months before trial and the general nature of his comments placed the statements within the rule's safe harbor.
Six months later the criminal case was tried to a jury in August 1988 and Sanders was acquitted on all counts. The trial judge questioned the jury venire about publicity, but not a single juror indicated any recollection of Gentile or his press conference. The State Bar of Nevada then filed a complaint against Gentile alleging a violation of Rule 177. Following a hearing, the Southern Nevada Disciplinary Board found that Gentile had made the statements and recommended a private reprimand. Gentile appealed to the Nevada Supreme Court, which affirmed the decision of the board.
