The belongings of that poor girl were identified and confirmed to be those of the two deceased's daughter and sister.
The Assistant Priest from Angale had specifically made a trip to Vism Town for this, and according to his report, the youngest daughter had calmly accepted everything.
Their family had filed a missing persons report six years ago; after six years, the tears had likely already dried.
So this did not prove anything.
As for the three suspects,
first, there was the town mayor's second son. After meticulous investigation, it was confirmed that this young man had no issues, and with the aid of "Detect Lies" and Durin's dual AI detection, this young man had cleared himself of any suspicions—in Durin's eyes, this teenager, only fifteen, was the least likely suspect.
