I’m not really a great observer so I can’t figure out the murderers for the life of me (and brute forcing would not be an attractive alternative) and since they don’t tell you whether you made 1 or 4 correct choices, I have no idea on what I got right but these are my suspects…
Ko’s murderer - Clues are really vague for me… I think Pat…
Nikaido’s murderer - The way he says “Business is business” reminds me of Glen, so I chose that
Pat’s murderer - Only person on the boat is Amanda (and Marina but she can’t possibly be the murderer for obvious reasons)
Amanda’s murderer - Mayako, see final scenario
Mido’s murderer - Mayako, see final scenario
