He was there for the golden age of smuggling — and he's still standing. That tells you everything.
Brian Heder is an officially confirmed GTA 6 character: a classic drug runner from the boom days of Keys smuggling who still moves product through the boat yard he runs. The fact that he's survived this long in that business, per Rockstar's own framing, says all you need to know about how he operates.
At the story's start, Brian employs protagonist Jason Duval and houses him: Jason lives rent-free in a Heder property in exchange for help with local shakedowns. Rockstar's bio also names Lori Heder — Brian's third wife — who runs the boat yard alongside him and, per official materials, is comfortable with a pistol or a rifle in hand.
Rockstar's materials are pointed about the arrangement: this isn't the kind of job you simply walk away from, and having Brian Heder do you favors isn't exactly good news either.
Brian runs Brian's Boat Works & Marina in the Leonida Keys — the "legitimate" business that fronts his smuggling trade, and where Jason Duval starts out. He runs it alongside his third wife, Lori Heder.
