Brian is the youngest known child of Beverly Johnson and the sibling of Carl, Sweet and Kendl. He likely bore a strong resemblance to Carl, as Emmet initially mistook Carl for Brian when they first met, though this could simply be a result of his borderline-senility.
Brian was associated with the Grove Street Families due to being the younger brother of the gang's leader, Sweet. He had wanted to be in the gang, but he had either no time or a short amount of time in the gang. Brian lived in the Johnson House, Ganton, which is located in Los Santos until his death in the year 1987.
Brian was killed in 1987. The plot around his death is unknown, except that Carl himself was present and failed to intervene.
Sweet blamed Carl for Brian's death, which led to Carl leaving Los Santos for Liberty City for the next five years. Carl did not attend Brian's funeral, confirmed when Sweet says: "That's another funeral you ran away from, fool. Just like Brian's".
Events of GTA San Andreas
Brian's death plays a big role in Carl and Sweet's relationship.
In 1992, Carl returns to Los Santos after his mother, Beverly, was killed by the Ballas. He missed the funeral, making Sweet angry at Carl for missing another one.
