At this point Greenough could identify Roberts, the author of one of the letters to Cyril Wilcox, as the principal target of his inquiry. The same day Greenough formed the court, he spoke to a graduate student in business, Windsor Hosmer. He expected Hosmer, as proctor of Perkins Hall, to be a source for information about Roberts, but he proved unhelpful, either because he was an inattentive proctor or because he preferred not to be candid. He told the dean he knew that Roberts hosted parties, but caused no disturbance and broke no rules. He was given three days to monitor visits to Roberts' room and report both current and past visitors. On May 26, Hosmer gave Greenough a list beginning with Roberts himself, followed by the names of Kenneth Day and Keith Smerage, noted as frequent visitors, then Eugene Cummings and Nathaniel Wolff, and then two more of whom he was "inclined to think that neither is part of the group that has centered around Perkins." A few days later, Hosmer returned to report that the last two boys had objected to his inclusion of their names.
