So state inspectors and independent engineers released some preliminary reports from their investigation and... wow
Basically, they found evidence of multiple crashes / derailments that were covered up and never reported including one "very recent" accident where it damaged the brake structure when it derailed and the park painted over the evidence. The extended history of derailments apparently damaged the safety (upstop) wheel system and the structure itself. They're implying that they “either knew or should have known that the ride was operating in a manner that presented a serious risk of injury to patrons.” It seems obvious that they knew since they were painting over evidence of derailments but I'd imagine that the people filing this report can't come right out and say that.
Here's probably the most damning excerpt from the story:
Here's the full story
“After dismantling part of the support structure to gain access to the site of the accident, the engineer found evidence of a previous derailment that occurred after the ride was refurbished and initially permitted in 2013,” state officials said in their report. “There was also evidence of other derailments that likely occurred prior to that year. A review of department records determined that no derailments were reported to the department.”
The engineers said they found evidence of a “very recent” accident that was “very similar” to the June 14 derailment and impact on the brake structure, but the evidence of that earlier crash was painted over.
State officials said it appears the ride owners and engineer who signed an affidavit attesting to the ride’s compliance with all regulations “either knew or should have known that the ride was operating in a manner that presented a serious risk of injury to patrons.”
