The victim had connections — some of them straightforward, some considerably less so. Everyone on the island has their own story. Some are hiding something. Question anyone you want, ask them about anything you have found, and challenge them directly if their account contradicts the evidence. The investigation is nonlinear: go anywhere, follow any lead, revisit anywhere at any time. At any point, when you believe you know the answer, you can make an accusation. Build your case, name the killer, and prove it. The killer is somewhere on this island. Do not rule anyone out too quickly.
