Lamar Davis is the player's first contact in Los Santos.
Lamar is a member of the Families street gang. Having met the player through Lifeinvader, Lamar welcomes him/her at the airport and proceeds to show Los Santos to the player. He's also the one who introduces the player to Gerald.
Gerald is an associate of Lamar Davis, and one of the player's first employers in Grand Theft Auto Online.
Similar to Lamar, Gerald is associated with the Families. He is a major drug dealer who is involved with raids on drug deals. Gerald often requests the player to attack drug deals, steal the merchandise, and bring it back to Gerald's apartment.
Simeon employs Lamar in his dealership, and later forces the player into working with him after giving him/her a free upgrade in Los Santos Customs. He often requests the player to either repossess vehicles or damage other dealerships.
Simeon also requests the player via messages to obtain and deliver specific vehicles to his garage at the city's docks.
Lester Crest is a strange, socially awkward man with a great deal of experience with technology and computing.
He is introduced upon reaching rank 10; Lester invites the player to his home and informs him/her of the player's growing reputation, before warning him/her for that. Lester introduces the bounty system, in which one player can place a bounty on another player so other players will try to put the bounty down.
