Returning GTA 5 players, get ready to solve a chilling murder mystery as Michael.
If you are a returning player of GTA 5 on the 'Enhanced' version of the game (PS4, Xbox One or PC) then you will be able to access exclusive "returning players only" content. One such piece of content is known as the 'Michael's Murder Mystery'. It is a side-mission in which you solve a mysterious murder. Upon successful completion of this side-mission, you will unlock 2 Vintage Noir Filters which you can apply on your display and play the game with those filters on.
The side-mission can only be played as the protagonist Michael. Please also make sure you have completed the story mode mission 'MELTDOWN' (it involves Merryweather agents going to Michael's home) before you attempt this side-mission or else it won't work.
When you find these clues and murder related content, you will hear a bass impact sound effect followed by a film reel sound effect which fades out. Then you will see a quick save icon on the bottom right corner of your screen. This indicates that you have found the clue successfully and that you can move onto the next one.

The Clues
In order to start solving this murder mystery, the first thing you need to do is to find the four clues around the Vinewood area. These four clues are engraved messages on the walls which lead to the next part of the mystery. These clues can be found at the locations listed below.
Clue 1 — The Gentry Manor Hotel
You can find the first clue in The Gentry Manor Hotel. The clue is in the backyard right after the pool. You will find the message engraved into the wall next to an archway. The messages reads:
