It was detained on 06/19/████ and has been more or less compliant. It's known abilities are teleportation or phasing through mirrors and appearing in a different mirror, it is unknown as to how it does this, but it is speculated that SCP-xxxx uses these mirrors as doors to other dimensions. Previous interviews has shown that SCP-xxxx becomes violent and agitated when asked too many questions about its past, no further information on the subject has been found.
Tests have shown that SCP-xxxx can enter a mirror by snapping its fingers within 5m of a mirror or reflective surface. SCP-xxxx has also been seen to show itself inside the mirror before luring its victim in, reaching through the mirror, and attempting to pull it through. Tests have also shown that no subject has ever been able to be successfully pulled through, SCP-xxxx will repeatedly bash subjects head into the mirror until subject is dead. To which, SCP-xxxx will mutter the word "disappointing" and continue to lure subjects in. Although it is work noting the majority of SCP-xxxx's victims have either been females with brown hair between the age range 18 to 20 or males with dark black or brown hair between the age range of 18-21. It is speculated that SCP-xxxx is attempting to find someone with a similar ability to his but has been otherwise unsuccessful.
