Saying "I know what you did last summer, so confess now or else" is not exactly an accurate question.
Even though it took you several pages to bring into Sheikah's target into the mix and as such "your" information was verified (I say yours like that because you could garner it from a potential mafia teammate?) but it would've been much more productive to give a little more than "I still know what you did last summer, now confess or I will post this again".
My guess would involve throwing a barrel at them, but it's been revealed to be... a hammer? Of all things. Most suspicious.
