This Is The Number One Unsolved Mystery In San Francisco And It Will Leave You Baffled

San Francisco has undeniably faced some turbulent events in its storied history. But it hasn’t quite let go of one particularly notable case that has never been cracked: the great unsolved mystery in San Francisco of the Zodiac Killer.

Hollywood’s Version

David Fincher directed the 2007 film Zodiac based on two books written by the political cartoonist Robert Graysmith (played by Jake Gyllenhaal), who worked at the San Francisco Chronicle when the Zodiac Killer was active. He became obsessed with the case after attempting to decode the cryptic letters.

The case of the Zodiac Killer remains open in San Francisco, Vallejo, and Napa and Solano Counties, and it’s still the area’s number one unsolved mystery.
