Fayçal Ziraoui is a French-Moroccan business consultant and engineer who claimed in 2021 to have solved the Z13 cryptogram and Z32 cryptogram. He read Z13 as “Kayr” — proposed as a typo of “Kaye” — linking it to suspect Lawrence Kane, and read Z32 as the coordinate phrase “LABOR DAY FIND 45.069 NORT 58.719 WEST,” which he said, under a magnetic-field coordinate system, points to a school in South Lake Tahoe. Many Zodiac researchers disputed his findings; the FBI and San Francisco Police Department declined to comment, and anonymous law enforcement officers told the San Francisco Chronicle they did not believe the solutions were correct.
Conflicting accounts
Ziraoui asserted his solutions were valid; the broader research community and law enforcement sources were skeptical.
