|Buffy the Vampire Slayer: Bad Eggs (1998) [Tector Gorch]: Devoured by the Bezoar monster.
From Dusk Till Dawn 2: Texas Blood Money (1999) [Deputy Edgar McGraw]: I vaguely recall that he was killed in this movie, though I don't remember the details. (He has reprised the role in several more Quentin Tarantino and Robert Rodriguez movies, though those have been explained as taking place before this film.)
Red State (2011) [Mordechai]: Shot in the chest in a shoot-out with John Goodman during the ATF's raid on the cult's compound. (Thanks to Tommy)
