ICE agents have been leaving cards on the vehicles of undocumented immigrants, often containing messages implying threats of imminent deportation. In Colorado, immigrant rights group Voces Unidas reported that family members discovered customized ace of spades "death cards" bearing the address of the ICE Denver field office after agents detained 10 Latino community members. According to the report, agents used fake police lights to pull over the vehicles, then left them abandoned with doors open, engines running and hazard lights flashing.
