 Between August and October 1956, Hannam collected a significant number of witness statements, mainly from the nurses and relatives of Adams' deceased former patients who claimed that these had been heavily drugged by Adams, were injected with unknown substances and had become comatose or unresponsive.By mid October 1956, Hannam had drafted his initial report for his Chief Superintendent.The Chief Superintendent was initially dismissive of the case Hannam presented, considering it was speculative, based on rumour and could not be proved; the Commander of 'C' Division agreed and the Director of Public Prosecutions asked Hannam to obtain more evidence.
