My first thought is that those two-role results are a bit of a waste. Giving the Investigator three roles that are definitely not mafia makes them too powerful by helping whisper games; so it'd be better to move "obvious" roles into those (because even if a Jailor is generally easy to confirm, there's still a huge difference between knowing they're Town the moment you investigate them, and having to ask or force them to reveal. With a three-Town result, I can start whispering them results immediately; if it's eg. Mafioso, Vigilante, Retributionist, then I can't)
Specifically, Jailor, Retributionist, Mayor makes the Retri auto-confirmed on investigation, which seems like a bad thing. (Retris can confirm, yes, but they have to use their ability to do so, and can be roleblocked.) I suggest moving it to one of the two-result ones, either:
Mafioso, Vigilante, Retributionist, or
Spy, Blackmailer, Retributionist.
Possibly also move the Jailor and Mayor the same way. So:
Mafioso, Vigilante, Jailor, (Your target is a killer)
Spy, Blackmailer, Mayor, (Your target is a master schemer.)
Invest, Consig, Retributionist (Your target seeks the truth.)
Or some variation on these. This way, a Jailor could still be forced to reveal by an Investigator, which I think is a good thing. It also opens up the final role as fringe claim-space for a Mafia member who can't claim their more reliable option for whatever reason.
Jester, Framer, Witch
Your target delights in the pain of others. They could be a Jester, Framer, or Witch.
We put a lot of thought into this result actually. At first glance it may seem kinda of silly that all these evil roles are paired up, but the kicker is the Framer. The Framer being able to frame others as having these results will make people very cautious we feel. The Framer and Witch are both fairly common roles in the game, and having these evil roles that you want to kill being matched up with the Jester should make players wary of hanging players. We feel that this will help give the Framer and Witch both more claim space, and even the Jester if they want to do some sly double fake outs. We feel that these results will lead to more lynchings of Jesters, and more lynchings of Framed targets which will bring down the Towns win rate.
This weakens the Framer a bit, though (because people may be reluctant to lynch people they frame, if it's an Investigator they happen to fool.) And the Framer is already really weak overall, since anyone they visit is auto-confirmed as not Mafia to the Spy, which is far more likely to happen than an Invest or Sheriff visiting your target the same night you do.
The basic way Framers work needs to change, though, so I wouldn't worry too much about this one... I'm just pointing it out. (Personally, I suggest making the Framer fool the Lookout and Spy as well; for the Lookout, make it so anyone who the Framer frames appear to visit whoever the Mafia killer attacks as an extra visitor; and for the Spy, make it so the Spy doesn't see any Mafia visits to the person the Framer visits, ruining attempts to determine the Mafia by elimination.)
