San4San

San4San is an active Haitian street gang based in Vice City, Leonida. It is also known as San 4 San and S4S.

The gang first appears publicly in a High Rollerz Lifestyle social-media video in the first trailer. At a customized car meetup, a man wears a San4San chain.

In the second trailer, the name is visible on a mural on the western side of a derelict warehouse in La Perle. The mural includes the words "S4SLIFE".
