The son of an Oklahoma Highway Patrol trooper was killed on Wednesday in a near-beheading at an apartment complex in Stillwater, Oklahoma. Isaiah Marin, 21, is charged with first-degree murder for the killing of Jacob Andrew Crockett, 19. Crockett’s brother, Jesse, described Marin as a “religious zealot” and “heavy drug user,” according to a court affidavit. Meanwhile, Marin’s brother provided a possible motive for the crime, saying that “in the past Jacob and Isaiah had disagreements because Jacob and Jesse were practicing witchcraft and Isaiah had strong Christian beliefs.” Stillwater police Capt. Randy Dickerson said during a news conference that Marin had “fantasized recently about committing multiple homicides.” Dickerson also emphasized that that the case is not related to recent cases of beheadings by Islamic extremists.
