3.3 The investigation
The investigation took three years to complete, although critical evidence emerged within weeks of the accident.
Some possibilities could be ruled out immediately. For example, there were rumours of supernatural forces at work that night, but very little solid evidence of the ‘Mothman’ emerged, either there or anywhere else. The Mothman was a demon purportedly haunting the bridge, which has supposedly appeared as a portent of similar disasters around the world. Such stories would have encouraged the investigators to speed their work so as to reassure the public that there were more rational causes of the bridge's fall.
