Retired homicide detective John Cameron believes the 77-year-old Edwards is indeed the Zodiac. Cameron, currently working for the Montana Board of Pardons and Parole, spent his summer researching the ailing Edwards, who is incarcerated in an Ohio corrections institute for a 1977 double murder.
There have been worse suspects. The more one studies what is known about Edwards, the more viable he seems. John Cameron told the San Francisco Chronicle that Edwards may well be “the most prolific serial killer that ever was.”
I’ve put out a message to Mr. Cameron to talk about the case, possibly to cover it for another online publication. If I can’t sell them on it, I’ll cover it in fuller detail here, later.
Meanwhile, John Cameron’s Facebook wall gives some hints at what he’s been up to.
