In 1986, a former friend began to suspect that San Francisco resident Richard Gaikowski (pictured above) was the Zodiac killer. That friend made the recordings featured below. Eventually, Gaikowski’s recorded voice was played to Nancy Slover, who had spoken with the Zodiac in July 1969. Slover’s reaction to Gaikowski’s voice is included below.
The audio samples of Gaikowski on this page were salvaged from old cassette tapes and are for informational purposes only.
