CBS’s Marshals has added Marque Richardson to its second season in a recurring role as Assistant US Attorney Patrick Burns, while Morgan Lindholm will return with an expanded part. The casting news signals further development of the Yellowstone spin-off as it prepares to continue storylines left unresolved by its first-season cliffhanger.

Production began in Park City, Utah in June, with Luke Grimes, Tatanka Means and Ash Santos confirmed to return; new episodes are due this autumn. Lindholm’s character Maddie is the estranged daughter of Cal, whose fate remains uncertain after the finale placed him and fellow marshal Belle in a gun attack, while season one averaged 20.4 million multiplatform viewers across its first eight episodes.
