On the side of the large barn advertising Cherry Pie at the farm in Great Chaparral, a message from the serial killer reads "Can you find me?" on the wall under a light.

GTA Online Serial Killer Clue 5 – Black Van

This clue is different to the others, as instead of having a fixed location there are actually five difference places in which the GTA Online serial killer's black van can appear. We'll list all of them below, so if you go to one and the vehicle isn't there then move on to the next location.

Once you've found all five clues, you'll receive a text message from the GTA Online serial killer. This reads:

"I'm sick of you sticking your nose in where it doesn't belong! Now I'm not going to lie... what happens next... won't be nice for you."

The Los Santos Slasher is now on your trail, though he will only appear between the hours of 19:00 and 05:00 in areas to the north side of the island. Go and hang around up there, until a red skull icon appears on your map – the serial killer spawns behind you, so be ready to fight!

The Los Santos Slasher is tough – he took three shotgun rounds from us before going down – but once he's defeated the GTA Online Navy Revolver will immediately appear in your weapon wheel, and you'll be $50,000 richer. This also unlocks the GTA Online Navy Revolver Challenge, which we'll explain next.

Once you have the GTA Online Navy Revolver in your possession, you'll need to get 50 kills with it to complete the Navy Revolver Challenge. Thankfully these can be NPCs, so you can just head into a populated area and start racking them up without having to take on other players. You'll receive a countdown notification of your total every 10 kills, and once you've done all 50 you'll receive another $200,000 in your account along with confirmation that an exclusive weapon in Red Dead Online is discoverable.

Red Dead Online Lowry's Revolver

To find the Red Dead Online Lowry's Revolver, head along the path west from Valentine until you reach the building we've marked on the map above. When you approach it, you'll discover it's a seemingly abandoned ruin, although ominously the shutters leading down to the cellar are wide open. Brace yourself, take a deep breath, and head inside...

Clearly you've discovered the den of a serial killer, and there are some pretty shocking sights if you fully explore the cellar. Inspect the bench to the side and open the lock box to find the Red Dead Online Lowry's Revolver, which is the Western equivalent of the GTA Online Navy Revolver. Lowry's Revolver has some pretty decent stats for a handgun, which makes it a decent addition to any cowpoke's arsenal. Now you just need to forget about the horrors you had to witness in that basement in order to get it!
