Justified has cast Alicia Witt and Edi Gathegi in its upcoming fifth season.

Prison Break’s Michael Rapaport will join the FX drama as crime lord Dale Crowe, a new nemesis for Raylan Givens (Timothy Olyphant).

Witt (The Mentalist) will play Dale’s sister Wendy, a paralegal who enjoys a flirtatious relationship with Raylan, Deadline reports.

Gathegi (X-Men: First Class) is cast as Dale’s henchman Jean Baptiste, a former member of the Haitian secret police turned merciless criminal.

Jere Burns – who has played the scheming Wynn Duffy on Justified since the show’s first season – has also been promoted to series regular status for the fifth season.

Walton Goggins – who also stars as Boyd Crowder – recently told Digital Spy that he is “very excited” for the new season, promising that the latest episodes will not “disappoint”.

Justified will return to FX in January 2014.
