Isaac McKinnon is a minor character featured in Red Dead Redemption.


Isaac is a Marshal who is normally found around the Blackwater Police Department Headquarters.


Isaac plays a small role in the missions "The Last Enemy That Shall Be Destroyed", where he is one of the Marshals that accompanies Edgar Ross.

Isaac also makes a minor appearance in "The Prodigal Son Returns (To Yale)" in which he stands guard at the train station in Manzanita Post along with Guy Crossfield.

Marston can find Isaac at the police station in Blackwater. If Marston has a bounty, Isaac and some other Marshals will track him all around West Elizabeth and New Austin.


  • Unlike most of the Marshals, Isaac's character model is not available in the Outfitter.
  • He appears to share similar facial features with Archer Fordham, and is often mistaken for Fordham during "The Last Enemy That Shall Be Destroyed" as he stands near Edgar Ross during John's death. His uniform is also similar.
