The maximum fine that Landis could impose was $29,240,000. To aid the judge in determining the sentence, Landis issued a subpoena for Rockefeller to testify as to Standard Oil's assets. The tycoon had often evaded subpoenas, not having testified in court since 1888. Deputy United States marshals visited Rockefeller's several homes, as well as the estates of his friends, in the hope of finding him. After several days, Rockefeller was found at his lawyer's estate, Taconic Farm in northwestern Massachusetts, and was served with the subpoena. The tycoon duly came to Landis's Chicago courtroom, making his way through a mob anxious to see the proceedings. Rockefeller's actual testimony, proffered after the judge made him wait through several cases and witnesses, proved to be anticlimactic, as he professed almost no knowledge of Standard Oil's corporate structure or assets.
