Man claims 'Zodiac Killer' is his father
BATON ROUGE- Gary Stewart was just a few weeks old when his father abandoned him on a set of stairs in an apartment complex.
Stewart was later adopted by a family in Baton Rouge, but as an adult he began to yearn for answers about his past, though he never thought it would lead him to the Zodiac Killer.
"I never set out to prove my father was a serial killer," said Stewart, "and when I discovered this horrible truth, I set out to prove that I was wrong about my assumption."
Stewart spent more than a decade searching for answers, digging through records, and comparing the various notes from the Zodiac Killer to what he knew about his father. What he found is detailed in his book The Most Dangerous Animal of All, Searching for my father... and finding the Zodiac Killer.
One smoking gun for Stewart, the ciphers left by the killer for police and the media, eerily matched his father's handwriting.
"He would say it was a conclusive match, but he had to put a caveat on there that is was virtually certain in the absence of original documents," said Stewart.
Now Stewart has to wrestle with his past, his biology, and push forward to his future.
"Genetics, absolutely, they're strong, but when you're raised in a family like I was raised in, I am a true testament of nature versus nurture," said Stewart.
The San Francisco Police Department still considers the Zodiac case open.
