YMMV / Criminal Minds S 5 E 19 A Rite Of Passage

• Alternative Character Interpretation: Is Deputy Boyd killing due to racism? He says before killing Ruiz that his victims can't be missing as they "ain't supposed to be here in the first damn place", but it's unclear if this is an expression of resentment or if he just means he's killing them because they won't be missed on account of not even officially being in the country.
• Complete Monster: Deputy Ronald Boyd kills undocumented immigrants because it allows him to assert a sense of power that he otherwise lacks, with over 40 victims to his name. When the Hispanic sheriff, whom Boyd loathes for being new to town, starts looking into the missing persons, Boyd sends her progressively more aggressive "messages"—severed heads in boxes outside the sheriff's office; a severed head on a pole in her front yard—until he finally kills her for sticking her nose into his business, while ranting that his victims aren't missing because "they ain't supposed to be here in the first damn place". Dismembering her corpse to pin the blame on drug kingpin Omar Morales, Boyd proceeds to murder Morales and most of his gang to cover his tracks; also because they're Hispanic. When his partner objects, Boyd shoots him and places the gun in the hands of the dead Morales.
