Zodiac Killer letter, April 20th 1970

Letter to the San Francisco Chronicle (1970)
by Zodiac killer

April 20th 1970. Claims 10 victims. Sent to the San Francisco Chronicle, it claimed to contain a cipher containing the murderer's name, though it was never solved. The 'blue meannies' (sic) mentioned in the letter is a reference to the blue meanies, the antagonists from the Beatles' animated theatrical film Yellow Submarine, which was released the year before.

This is the Zodiac speaking

By the way have you cracked the last cipher I sent you?

My name is—

I am mildly cerous as to how much money you have on my head now. I hope you do not think that I was the one who wiped out that blue meannie with a bomb at the cop station. Even though I talked about killing school children with one. It just wouldn't doo to move in on someone elses teritory. But there is more glory in killing a cop than a cid because a cop can shoot back. I have killed ten people to date. It would have been a lot more except that my bus bomb was a dud. I was swamped out by the rain we had a while back.

The new bomb is set up like this

Sun light in early morning. A & B are photo electric switches when sun beam is broken A closes circuit " " B opens " which makes B the cloudy day disconnect so the bomb wont go off by accid.

PS I hope you have fun trying to figgure out who I killed
