‘It’s not an unsolvable case’: has the Zodiac killer finally been found?

Author Jarett Kobek never intended to make the case the focus of his book but he may have solved the 50-year-old mystery

When author Jarett Kobek started researching the Zodiac killer for a book during the pandemic, he didn't want to become just another amateur sleuth claiming to have finally solved the case that's gripped America for decades.

Yet, that's more or less what happened. Kobek came across Paul Doerr, a San Francisco Bay area man who died in 2007, who he thinks is likely responsible for the killings and is the subject of his book: How to Find Zodiac.
