None as far as I know. There are enough similarities with everything else to think this incident is similar than last week's, though.

[Was Scien controlled or spurred into murdering, for some reason? Sora still isn't convinced about that, but...perhaps that's what happened after all, and now it was someone else's turn.

At least Todomatsu can be ruled out. He doesn't look in any state to be murdering anyone -- unless they find Viktor with his head cracked upon with a crutch]
