 All FBI-UIU agents operating across the mainland United States must be aware of a newly confirmed anomaly. The anomaly is a collection of humanoids which invade various homes and kill the residents, sometimes consuming them. These humanoids can enter a property only if they are invited inside. However they can imitate voices and identities. All UIU agents responding to murders must be aware it may be an instance of this anomaly and harm themselves suitably. The anomalous humanoids are vulnerable to iron and cannot be harmed by other means. All agents should retrieve iron ammunition from FBI-UIU safe houses so they may come at these entities. UIU agents recovered the body of the agent and the anomaly. The anomaly has been detained. Efforts are underway to contain more of the anomalous humanoids.
