Oscar Guzman is a minor character in Grand Theft Auto V.
If Trevor buys the McKenzie Airfield in Grapeseed, he can drop packages of guns off for Guzman's buyers, and will be paid for it. He tells Trevor that he has been north for around five years on-and-off, because there was too much competition south of the border in Mexico.
He's an independent gun runner that keeps a moderate profile in the crime scene, as he's avoiding making enemies with the most powerful Mexican gangs by making peace with the Vagos or paying off Madrazo Cartel, yet he's still competing with the Varrios Los Aztecas and the Marabunta Grande.
- Based on his voicemail, he is a cocaine user.
- Despite obtaining his personal phone number, he never makes any calls or can be called.
