In April 1977, Joe Conforte - one of Claiborne's former clients who owned a well-known Reno, Nevada, brothel called Mustang Ranch - was arrested on 10 counts of income tax evasion and faced a minimum five years in prison and $10,000 fine.
With Swanson neutralized, Yablonsky was able in 1983 to get the help of the IRS in returning Conforte to the United States in exchange for testimony against Claiborne.
