So here is an interesting one that makes it obvious why it is interesting to this particular forum:
New York City police continued to hunt a serial arsonist Sunday suspected of setting fire to seven homes since early November, while neighbors in the ravaged area say the firebug – who has taunted cops with coded riddles – is targeting only Jewish residents.
“Decode this message to find out the person who caused the fire,” the note read, according to DNAinfo.com.
The note also had rows of numbers and letters, and a Sudoku-loving cop quickly solved the message, which turned out to be the name of a Forest Hills resident. Police have determined the person had nothing to do with the fires.
“Initially we looked at it as a lead,” Boyce said about the note during a recent press conference, adding that police "don’t believe he is involved in the fire at all."
Apparently this guy is not a good at coding as Z, but the fact he is leaving these at his sites makes me think he knew of the Z ciphers. I would love to see one of the codes from this guy just to see if they are laid out anything like the Z ciphers.
