But... True crime I take very seriously and have put in well over 1,000 hours of research in the last 15+ years. My personal theory, based on a ton of research, was that "Zodiac" was an MK Ultra project that involved a psychiatrist in San Francisco, and I thought the Unabomber may have even been involved. It was a good theory but I have never claimed any of it as fact because it was just a theory with no hard evidence.
My friend didn't give me a name or any details, but him saying he has identified the killer is pretty neat. He is a forensics expert and has a great team working for him. He's making a documentary and that is when the name will be revealed. Not sure when that will be.
