Deliver an unsuspecting victim to the Altruist Cult. [Bronze / 5G]

Warning: this trophy / achievement is missable if you deliver all people from random events to their target destination instead of the Altruist Cult.
Only Trevor can deliver persons to the Altruist Cult. It won't work with any other character.
You will have multiple opportunities to get this. All of the random hitchhiker events work (there are 4 of them). These events will occasionally show up as a blue dot on your mini-map when they are nearby. One hitchhiker can be found at the street on the southern foot of Mount Chiliad. The random events don't always show up, but have fixed locations. If you cannot find the hithchiker, simply drive in another direction for a quarter mile and return. The event will spawn sooner or later if you keep doing this.
Drive to the blue dot on the map and wait until the hitchhiker gets into your car. Instead of going to the target destination you must drive to the Altruist Cult. It's marked with a big "A" on your map, on the west side of Mount Chiliad. This symbol will only show up once the hitchhiker is in the car. Deliver the person to the cannibals of the cult and you will get some money as well as the trophy / achievement.
