The coroner arrived at the scene on the day of the disaster and swore in six community leaders that afternoon to serve as a jury investigating the death of Superintendent Huyck. Informal testimony had been taken on May 19 and the formal coroner's inquest started on May 23. The Clinton County prosecutor conducted the examination, and more than 50 people testified before the jury. During his testimony, David Hart stated that Kehoe had told him that he had "killed a horse" and "The New York Times" reported people as saying that Kehoe had "an ungovernable temper" and "seemed to have a mania for killing things". Neighbors testified that he had been wiring the buildings at his farm about that time and that he was evasive about his reasons.
