Whilst I have no knowledge of this occurrence at all, if, as has been suggested, the flight crew failed to own up to the true nature of what happened for some time, one might question the crew's perception of their local Just Culture.
The worse the outcome, the harder it is for management to apply it properly, especially when their higher management are clamouring for a scapegoat. Just Culture is as much about the organisation as it is the individuals involved. I hope that these questions aren't lost in the aftermath of the investigation.
