This is indeed Kenobi's notes on the matter.
Other than the pre-trial hearing deails themselves (Kenobi notes that the hearings have been ridiculously delayed as the situation was debated in the Senate), the highlighted parts are abouyt what is relevant to your particular task.
The Viceroy says he is ecertain that someone is trying to kill him. Kenobi does not think the Viceroy means the Sith; he thinks the suspicion is purely political. He also thinks it is part of an overall attempt to delay or defer the trial still furhter- almost certainly a lot of negative influence is being placed on the Senate. Luckily, the Chancellor is on-board the pro-trial side (hardly a surprise, if you think about it- Naboo is his homeworld!). In fact, talking of the Sith, the Viceroy has never mentioned anything of the mind- Kenobi's entire case has rested on statements form other people. As he told you, al he has established is that the Federation was taking its orders from an mysterious unidentified figure who contacted the leadership remotely. Qui-Gon was sure that the Sith were manipulating the situation, and it also seems like that the Sith assassin was sent to aid the Federation when Qui-Gon rather ruined their plans. This whole Sith hypothesis, then, is an extrapolation of the Jedi investigation and nothing to do with the Viceroy's pleas for protection.
The source of the Viceroy's pleas stems from the fact that last month, his cousin was assassinated on Neimodia.
Now, Kenobi notes that Neimodia is a very unpleasant place indeed- in fact, the tone seems to be that the entire planet is in violation of a hundred Republican laws but gets away with it due to political lobbying- kind of place you loathe, Marcus. Assassination is a commonplace means of advancement- power struggles are always vicious. Such a struggle was expected after thr Viceroy's arrest
But... actually it never happened,. Somehow- again going back to the obscure politicising behind the trial- the Viceroy has stayed in power! In that context assassining his couisn-a possible successor- seems pointless. Achieves nothing. There could be a thousand other reasons why this has happened. Such things happen a lot. But it is just slightly odd enough for the Viceory to make out it is the start of a pattern of executions that will include him. Hence... all this.
However. There is one disturbing post-script. Gunray hired a private investigater to look into his cousin's death. Now, this is a little extreme- the investigator has been murdered as well. At the time of writing, kenobi was awaiting the autopsy report.
The autopsy report is attached to the file- it arrived after Kenobi handed over to you.
