A ntsb investigation into the incident was announced the afternoon of may 29th, and is on-going. As additional information is publicly released during the course of the ntsb investigation, future supplemental reports will be updated to reflect those facts. The total damages from the incident are still being determined. The figures used in this report were based on publically available valuation data from the mahoning county auditor website and are only a preliminary estimate.
