Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures:
SCP-XXXX is to be kept in a standard humanoid containment cell located in site-██. No object that might be used as a weapon is allowed to be acquired by SCP-XXXX, and thorough search of its cell must be carried out every 24 hours. All personnel assaigned to SCP-XXXX should be made aware of its history, and take precautions when interacting with it. In the event of SCP-XXXX's death, the body should not be moved, except for the purpouse of pre-approved experiments.
Description:
SCP-XXXX is a caucasian male, aged 34. Every 24 hours or less, SCP-XXXX will be involved in some accident or interaction resulting in its death. Exactly 12 hours following SCP-XXXX's death, its body would dissapear, and a man, physiologically and psychologically identical to SCP-XXXX, would appear in the spot where SCP-XXXX had died, baring all of SCP-XXXX's memories, including recollection of its death, and having the same anomalous traits. To date, no attempt to prevent SCP-XXXX's death were succesful, and further attempts to do so were discontinued as a waste of Foundation resources and manpower.
History:
SCP-XXXX's anomalous properties were discovered and brought to the Foundation's attention following SCP-XXXX's conviction as the "West Bank Killer", a serial killer responsible for at least ██ counts of murder and an additional attempted murder. SCP-XXXX was convicted and, one year later, executed in █████ ██████ Prison, only to reappear in the execution chamber exactly 12 hours later, after which it was brough into Foundation custody.
