 If you can see this message from the Sector Crime Patrol, then you must be aware of an individual who threatens the safety of your family. A pale male of European descent has been sighted in areas near you. This individual is extremely tall and always appears naked. He has been known to stalk and kill all members of households in isolated rural areas every year, from December 22nd to January 2nd. He only attacks households which fulfill the following criteria, at least one child under the age of eight, snow cover at the time of attack. This individual will often attack and kill all members of a family in a brutal and ritualistic fashion. Otherwise, they will sneak through the house and leave small and through some gifts throughout the house made of human remains. The Sector Crime Patrol has yet to detain this individual, but you can help arrest this dangerous criminal. If your household fulfills the attack criteria, please report anything unusual to Sector Crime Patrol and your local authorities. You should especially report your children seeing anyone outside your house, footsteps on the roof of your house, or an unpleasant odor. Report these unusual phenomena, and the Sector Crime Patrol may be able to detain this individual before he harms anyone else. All SCP Foundation personnel are advised. SCP-4666 is entering its active phase, and may soon begin to attack households at 40 degrees north latitude. All Mobile Task Forces stationed at above 40 degrees north latitude must be ready to rapidly deploy and contain SCP-4666. A Foundation Front Company, Sector Crime Patrol has disseminated information publicly suggesting SCP-4666 is an anomalous criminal. This will hopefully lead to civilians reporting SCP-4666 related activity, and may facilitate Foundation containment. The SCP Foundation will secure and contain SCP-4666, and protect all members of the public.
