I'm not a mobster; the clue is too obvious. The killer probably planted something similar because the GM wouldn't eliminate me so easily. Although, of course, the only clue is confusing, but maybe it's a hint about moldy cheese... do we have any foodies here?
P.S. Additional alibi: I had guests yesterday, and I only went online in the morning. After the guests left, I watched anime and went to bed.
And it's clear that Mold is the villain...))
By the way, the third murder is most likely the work of a blood brother...))
