“The biggest tax evasion case in US history” is levelled at Marc Rich in 1983, containing charges of criminal fraud, wire fraud, racketeering, and flouting a ban on trading with Iran during the 1979-81 hostage crisis. The charges carry with them a potential sentence of 300 years. Rich flees the US for Switzerland, and is put on the FBI top-10 most wanted list.1
