First he was shot dead on "Sons of Anarchy," but now the guy who played Sheriff Vic Trammel on the show is facing the death of his real-life marriage ... TMZ has learned.

Glenn Plummer -- who you also might remember as Bobby Johnson in the kick-ass gangsta classic "South Central" -- has been hit with divorce papers by his wife of 12 years DeMonica Santiago-Plummer.

According to the docs, filed in L.A. County Superior Court, DeMonica is seeking full legal and physical custody of the couple's two children.

FYI -- DeMonica's kinda famous in her own right -- she was a member of Motown R&B group The Good Girls in the late 80s.
