Burying the lede?
A USNI News article on the charging the the McCain and Fitzgerald commanders noted that three Fitzgerald junior officers were charged, but contained the mention:
A chief petty officer also faces a dereliction of duty charge that has already been preferred related to the McCain incident.
That’s news to me. I again searched the report and found no relevant mention of “chief”. The main mentions of a”chief” were in the context of post-collision rescue/damage control efforts. I wondered whether that related to post-collision acts.
Thus, perhaps the chief either did something so significant or clearly criminal that they charged him before charging the CO or something so unrelated to the cause of the incident that they charged him as the result of a separate, less detailed investigation.
