A bloody trail runs through Blaine County: a message on a wall, a severed hand, a bloodied machete, a handprint and a van packed with grisly evidence. Find all five clues — the first four stay in fixed locations, while the van can appear at one of five spots. Once the trail is complete, the Los Santos Slasher will come looking for you between 7 PM and 5 AM. Take him down and claim the Navy Revolver.
