First, note that most of this is based on my trust on Rizu and bash. I trust Rizu 99%; I'm still a little suspicious about bash, but I'd say he's most likely town (or a very skilled BO).
Link's killer can be Miaka, Yuri (or Meme). I do think Meme is town though.
Cinna's killer can be Kleene, Yuri or Moon. I'm inclined to trust Moon now.
How I narrowed the list:
I cleared up Moon, Kleene and Henry for killing Link using SI.
I said I trust Rizu and bash, so they are eliminated from the suspect's list.
Rizu cleared Jecka using her actions (both for killing Link and for killing Cinna).
This leaves us with Miaka, Yuri or Meme.
I investigated Miaka killing Cinna the night she was killed (turned out as false).
Bash said he cleared Meme for killing Cinna (won't say what action he used because obvious)
Henry was arrested that Night.
For same reasons as above, Jecka and Rizu are clear. This leavs us with Kleene, Yuri or Moon.
After that Moon said Day 4, I'm inclined to trust her.
I hope I haven't missed anything.
So if either Rizu or bash turns out to be BO, you know who they said they "cleared".
