No one is going to mistakenly confirm a death. Let's see who confirmed who's deaths.
-Shannon: 'each child confirm their parents died' which might be a lie. They can't make a mistake, but they might have not even attempted to confirm deaths.
-Kanon: 'Nanjo and I confirmed Genji was dead' same as above.
-Maria: 'All of the victims died instantly'. This doesn't confirm anything.
-Nanjo confirmed Krauss and Natsuhi died, which must be true.
-Nanjo confirmed Shannon died, which must also be true. This extends to Kanon.
-Nanjo confirmed Gohda and Kumasawa's deaths too.

In total: Nanjo, Krauss, Natsuhi, Shannon, Kanon, Gohda, Kumasawa are definitely NOT culprits. I'm very confident in this.
