Heston Jameson

Heston Jameson is the warden of Sisika Penitentiary and the brother of Archibald Jameson, who operates a mining company in Annesburg. Before the events of Red Dead Online, Heston directs Officers Jenkins and Milliken to take a group of prisoners from Sisika for a work detail. The prisoners include the protagonist, and Horley, Went and another gunman free them during the transfer.

Later, the government orders moonshiner Lemuel Fike and racketeer Stan Reardon sent to Sisika. Jameson prepares a Prisoner Transfer Document that identifies where Reardon will join the convoy carrying Fike. During "Blood is Thicker Than 'Shine", the protagonist takes the document from lawmen near the Brush Fire, then uses its information to intercept the convoy, free Fike and bring him to Maggie.

In Red Dead Redemption 2, Jameson attends Mayor Henri Lemieux's party in Saint Denis. He discusses law and order with Dutch van der Linde and Hobart Crawley, opposing Dutch's more progressive position alongside Crawley. Jameson and Crawley leave the conversation disliking one another. Much later, Milliken tells Arthur Morgan and Sadie Adler that Jameson runs Sisika, but guards at its gate say the warden is in Saint Denis as they arrive to free John Marston.
