Los Santos hides many dark secrets, but few side missions are as memorable as tracking down the infamous serial killer in GTA Online. This chilling investigation sends players across Blaine County to uncover disturbing clues, culminating in a deadly encounter that rewards you with an exclusive weapon and a hefty cash bonus.

Whether you are low on cash, love collecting unique weapons, or simply want to experience one of GTA Online’s most atmospheric mysteries, this guide walks you through all serial killer clue locations, how to trigger the encounter, and how to finish the Navy Revolver challenge efficiently.

What You Get for Completing the Serial Killer Investigation

Before diving into the locations, it is worth knowing why this hunt is so popular:

• Unlock the Navy Revolver

• Earn an instant $50,000

• Access the Navy Revolver Challenge for an additional $250,000

For a relatively short side quest, the payout is excellent, especially for newer players building their criminal empire.

All Serial Killer Clue Locations Explained

There are five total clues you must inspect. The first four always spawn in fixed locations, while the fifth clue (a black van) can appear in one of several areas. You must find any one of the possible fifth spawns.

Clue #1: The “Can You Find Me?” Graffiti

Your investigation begins in Great Chaparral. Look for a cryptic message sprayed onto a building wall. The graffiti sits beneath a hanging lamp, positioned between two windows. Interacting with this message officially starts your hunt.

Clue #2: The Severed Hand

Travel north to the Grand Senora Desert, near the Sandy Shores airstrip. At the northwest end of the runway, check the broken section of fencing. On the ground, you will find a severed hand—an unsettling confirmation that something far worse is coming.

Clue #3: The Bloodied Machete

Next, head toward Grapeseed, just beyond its small airstrip. In the northwest area, inspect the outer wall of a wooden barn. Leaning against it is a machete covered in dried blood. Examining it adds another piece to the puzzle.

Clue #4: The Bloody Handprint

Your fourth stop is Paleto Forest, behind the Bayview Lodge. Walk around the back of the building and look to the right for a small wooden shack. On its door is a clear, bloody handprint. Inspecting this final fixed clue pushes the mystery toward its conclusion.

Clue #5: Finding the Serial Killer’s Black Van

The last clue does not have a single guaranteed location. Instead, the black van can spawn in one of five possible areas. You only need to find it once.

• Near a silo by the Palmer-Taylor Power Station

• Under a highway bridge in the Grand Senora Desert, close to the train tracks and You Tool

• In the swamps of Lago Zancudo

• Cassidy Creek in Raton Canyon

• Along the train tracks in Braddock Pass, near the tunnel

When you locate the van, inspect it to complete the investigation phase.

How to Trigger and Defeat the Los Santos Slasher

After inspecting the fifth clue, you will receive a threatening text message from an unknown number. This confirms the killer is now actively hunting you.

The slasher can spawn between 7 PM and 5 AM in-game, most reliably in northern areas of the map. An open, rural location like Sandy Shores Airfield works exceptionally well.

Tips for the Encounter

• Stay in an open area with good visibility

• Keep a firearm ready

• The slasher charges with a machete, making him easy to eliminate at range

Once defeated, the reward triggers immediately.

Rewards: Navy Revolver and Cash

Killing the Los Santos Slasher grants you:

• $50,000

• The Navy Revolver added to your inventory

If the weapon ever disappears from your weapon wheel, do not worry. You can reclaim it for free at any Ammu-Nation.

How to Complete the Navy Revolver Challenge Fast

The Navy Revolver Challenge requires 50 kills using the revolver. These kills do not need to be other players. NPCs count, making this challenge very easy with the right setup.

A popular method is launching the Rockstar-created mission Pier Pressure. This mission spawns endless NPCs at Vespucci Beach without building a wanted level, allowing you to farm kills quickly and safely.

Complete the challenge and the extra $250,000 is deposited into your account.
