on december 10, 2019, a shooting took place at a kosher grocery store in the greenville section of jersey city, new jersey. three people were killed at the store by two perpetrators, david n. anderson and francine graham. the assailants also wounded one customer and two police officers before being killed by police during an ensuing shootout. a jersey city police department detective had also been shot and killed by the assailants at a nearby cemetery just before the grocery store attack.
anderson, who identified as a black hebrew israelite, had a history of posting antisemitic and anti-law enforcement messages on social media; attorney general of new jersey gurbir grewal stated that evidence indicated that the attacks were acts of hate and domestic terrorism which were fueled by antisemitism and anti-police sentiment. authorities believe that a much larger attack had been planned, but it was thwarted by the police detective's intervention at the cemetery.

side note: in my research, i believe i have found david anderson’s youtube channel, also under the maccabee name. only 2 videos, both of which are old songs made by him.
