 Item number SCP-668 Object Class Euclid Special Containment Procedures Revised As of data expunged, no special containment procedures, aside from standard security, are required. SCP-668 is to be transferred to a locked safe deposit box at Site-19's high-value item storage facility. Standard defenses against intrusion, explosive, chemical, biological, and memetic are to be in place at all times, according to standard operating procedure. SCP-668 may only be removed from its safe deposit box by personnel with security clearance two or higher. Individuals wishing to make use of SCP-668 outside Site-19 must first submit a Form 668 requested course of action form to 05-11 and be fitted with an explosive kill switch collar on a 24-hour timer before taking SCP-668 into the field. An auditing officer with security clearance four or higher must confirm that SCP-668 has been returned to its safe deposit box before the collar is deactivated. Description SCP-668 is a 33-centimeter, or 13-inch, chef's knife with a rosewood handle and full tang construction crafted at some point from the late 1930s to the early 1940s. When first acquired by field operatives, SCP-668 was in badly rusted condition with heavy pitting from blood stains and other bodily fluids trapped in micro crevices within the blade. Following thorough analysis, these irregularities were removed for aesthetic purposes. This has had negligible, if any, effect on SCP-668's special properties. The first recorded appearance of SCP-668 was in the 1960s during the infamous Data Expunged case. Data Expunged, a New York woman living alone, was allegedly raped and murdered by subject Data Expunged. Despite the fact that 38 witnesses reported hearing the attack, none of them attempted to aid the young woman for over six hours until her eventual death. Whether the item received its properties due to this event, or whether it had them beforehand, is a matter of debate. See Dr. P***'s paper regarding the bystander effect versus Dr. P***'s theory regarding psychic imprintation. What is clear, however, is its current properties. When carried by a human or humanoid entity with violent intent towards another human or humanoid entity, SCP-668 broadcasts a psychic signal that renders all sentient beings with a psionic resistance index of 97 or lower incapable of assisting the victim. Affected entities report a sudden sense of apathy while under SCP-668's influence. Sensory input is not affected, and affected entities report feeling revulsion and horror, but are simply incapable of acting, even indirectly, to assist the victim. Meanwhile, it renders the victim incapable of defending themselves against their attacker. Tests using Class D personnel have shown no upper limit in the number of entities affected by the psychic resonance. In one test, 12 Class D personnel due for first of the month termination were placed in a room alongside a researcher who was told to randomly select one test subject for death. The researcher killed all test subjects, one by one, despite their professed horror. Prior incidents have indicated the possibility of hundreds, if not thousands of deaths, due to SCP-668's unique properties. See Incident Report 668A regarding Maul Massacre and subsequent information blackout operations. Recovery of SCP-668 in such scenarios is problematic due to the item's psychic properties. Agents attempting to apprehend the subject during containment failure incidents are often themselves affected by SCP-668's so-called apathy field, resulting in casualties among Foundation personnel. Following incident 668A, standard retrieval protocol includes the use of a long-range sniper rifle, double-blind conditions, and three different agents working in tandem through carefully coordinated actions to prevent any of them realizing that they are actively opposing the subject. Because of the obvious apocalyptic possibilities, it is the recommendation of this panel that SCP-668 be designated a Keter-level threat and placed in high-level confinement. Incident Retrieval of SCP-668 13-inch Chef's Knife SCP-Involved SCP-668 Personnel Involved Data Expunged Date Location Description On date expunged City Police Department, precinct, responded to reports of a man attacking and killing bystanders with a large chef's knife at a local mall. Upon responding, officers discovered 15 casualties, most of whom had been ritually cleansed in a manner described by witnesses as horrific. Officers discovered the suspect, an escaped serial killer named henceforth referred to as suspect in the child's daycare area in the process of filaying and consuming a nine-year-old boy. Officers ordered suspect to cease and desist. Suspect did not comply. Officers then attempted to fire upon suspect but discovered that they were unable to pull the trigger. Officers then attempted to flee but found themselves unable to do so after suspect declared his intention to, quote, murder every last one of you motherf***ing pigs, end, quote. Suspect then proceeded to data-expunged, ending with Cynthia Wallace, a foundation operative embedded as an observer with the RPD. Despite being under severe psychic assault, Officer Wallace, a pseudonym, managed to activate her emergency transponder located in her belt while complying with suspect's orders to alerting the foundation of the situation. Mobile Task Force Pi-1, city slickers, arrived on the scene minutes later, disguised as an FBI special anti-terrorist task force. Pi-1 breached the perimeter at responding with the moment that Officer Wallace's vital signs telemetry ceased transmitting. Task Force members discovered suspect standing outside the department store on the third floor of the mall. The police officer's bodies were found suspended from the third floor railing, skin-flensed, and arranged in the form of wings, entrails removed, and trailing to the floor. Officer Wallace's body was found data-expunged. SCP operatives then attempted to terminate suspect, only to discover that they, too, were unable to fire their weapons. Team Leader- transmitted a Class-1 Type-73 memetic attack alert to command, and ordered the team to withdraw. This order failed when suspect stated his intention to, quote, find out what all your insides look like, end quote, rendering them helpless to escape. Involved Task Force members were subsequently remote-terminated. Using surgically installed cranial detonators, according to standard field protocol following psychic compromise in a field agent. Command elements then authorized Escalation of Force to Tier 2, severe collateral damage. Aerial bombardment was attempted, but failed when the pilots were unable to release their payload over the target. It was thus determined that the psychic field that prevents hostile intent toward subject may have an infinite range. Escalation of Force to Tier 3 was considered, but delayed while Dr. Gears suggested an alternative strategy with a higher chance to retrieve the item intact. Hypothesizing that hostile intent was required for the psychic controls to trigger, Dr. Gears suggested using Class-D personnel, undermined control by SCP-61. Previously prepped sleepwalker agents fitted with surgically implanted earpieces transmitting SCP-61 were given the following commands. D61-56 was ordered to give the following commands to the rest of the personnel through radio control. D61-56 was not given any indication as to the reason for said commands, to prevent the psychic defenses from triggering. Agents were able to order D61-56 to give the following orders, suggesting that the psychic defense may only be able to function through a certain number of iterations. More research is required on this issue. D61-59 through 70, 12 personnel were ordered to carry explosive charges to 12 predetermined points, opening gas mains along the way. Explosives were detonated in sequence, upon being given the final order by D61-56. D61-99, who fit the profile of the subject's preferred type of victim, was ordered to move to a predetermined location at the center of the mall to lure the suspect to the best location for both ensuring a kill and allowing for easy retrieval of the remains. Finally, 60 class personnel not under control by SCP-61 were ordered to capture the subject. These class D personnel were not expected to complete their mission and served as a delaying action while the mind-controlled operatives carried out their mission. The operation was a success. By utilizing multiple personnel, none of whom were aware of the significance of their actions, none of the personnel knew that their actions were related to terminating the suspect and were thus able to act freely. Suspect's remains were retrieved from the rubble by a bomb-defusing robot and placed in a box lined with SCP-148 before being retrieved by Foundation personnel. Following confirmation of capture, command ordered Tier 3, nuclear detonation, elements to stand down from Ready-5 status, and declared the incident contained. A cover story blaming the attack on terrorists was formulated and disseminated to the public. Controlled testing is determined that the suspect's weapon, 13-inch chef's knife, was the active agent in the incident, emitting a psionic command that data expunged. Suspect's remains are to be sent to RPD, along with a replica knife. The original weapon is to be designated a Keter-level SCP, SCP-668, and sent to Site-19 for further testing. How the suspect acquired SCP-668 is unknown at this time. It is further noted that the obsessive nature of the subject's method of killing may have contributed to the success of this operation. Subject carried out its killings in a ritualistic manner, maximizing the amount of horror, pain, and suffering inflicted on its victims. For this reason, Foundation personnel were able to keep him contained in an enclosed area, the mall, and formulate a plan of action. Should the subject have made the decision to leave the mall and continue its killing spree elsewhere, immediate Tier 3 response by a double-blind operator would have been the only possible method of containing the incident. End Incident Log Addendum 668A Following further testing, it has been determined that the test subjects wielding SCP-668 can be terminated through passive response, so long as the terminating agent is introduced before the subject takes possession of SCP-668. The Running Man Protocol is hereby approved for use with SCP-668, and the item in question is hereby reclassified as a Euclid-type object. Addendum 668B With the ending of the Omega-7 project, no further attempts to weaponize SCP-762 or SCP-668 are to be attempted. Addendum 668C With the ending of the Omega-7 project, no further attempts to weaponize SCP-682 or SCP-668 are to be attempted. Addendum 668D Request to reclassify SCP-668 under its original designation as a Keter-class object under review. Addendum 668E Request to reclassify SCP-668 under its original designation as a Keter-class object denied. SCP-668 will remain at Euclid classification. Lesson complete.
