 This unidentified man, known only as 3x, claimed to be a member of a secret international crime organization and ended two people's lives without any reason. The criminal claimed a man's life after catching him having an affair. But rather than try to conceal the crime scene, he began shuffling through the victim's pockets while looking for a strange slip of paper. He later escorted the victim's mistress to a bus and handed her a note before leaving that simply read, 3x3x097. Just days later, a second crime unfolded that perfectly mirrored the first crime. Days later, someone sent an ominous letter to a local newspaper that was signed by someone calling themselves 3x. 3x eventually sent a letter directly to the police, claiming to have been working for a Russian spy organization. He claimed that both of the victims had been affiliated with the organization as well, and that 3x had been selected to end the man's lives, but he never explained why. No further letters were ever received, and both crimes remain unsolved to this day, and 3x has never been found.
