the story is extremely sketchy and based on claims made by former cops who presented no evidence other than just saying they figured out it was him. no dna matching, a bunch of coincidences and a handful of people convinced this terrible dude they knew was secretly the zodiac killer. also worth noting, the original interview was given to fox news, which has a very strained relationship with factual reporting.

also worth noting which news outlets have picked up the story:

when you see fox news, the new york post, the sun, and TMZ, you need to be extremely skeptical, because none of them have a strong track record of factual reporting, and the latter three are more in the realm of sensationalist tabloids than legitimate news outlets
