Jefferson died Thursday, his rep Nicole St. John told The Hollywood Reporter. He announced in August that he had been diagnosed with cancer.

Born on April 7, 1970, in Houston, Jefferson received a BFA in musical theater from U.S. International in San Diego and and an MFA in acting from the University of Arizona. He landed his first onscreen role in Boys on the Side (1995).

Additionally, Jefferson held jobs as an acting instructor, voiceover performer, and producer. Relative Opposites, Dad Stop Embarrassing Me!, You Too, Bosch: Legacy, and Day Shift were among his other TV and movie credits.

St. John said Jefferson had several projects in the works and was in the “midst of a project that captured his unique and resonant voice. He had been looking forward to returning in the new year.”

The actor shared a trailer for The Burial on his Instagram last month: “It’s finally here and what a blessing it was to work on this film with an amazing group of actors. Foxx and Tommy Lee Jones along with an all star cast and my most important role to date.”

No information on survivors or memorial plans was immediately available.
