Imagine a 80+ years old senior citizen writing a letter to let the cops run around just to relive his good old days in the Bay Area.

Nah, probably not a Zodiac communication but I found the tone of writing and handwriting of this postcard very like the Zodiac so I will post the story about it here anyway.

The radio station at Volunteer State Community College in Tennessee received an anonymous postcard in the mail on Oct. 8 2015 signed “Green Light Killa” and reported the suspicious note to campus police, who then brought it to the Gallatin Police Department the same day.

The postcard, which was postmarked in Peoria, Illinois reads:
“Hello, you know what it’s like 2 watch a train hit a man you laid on the tracks. Trains make an awful mess of an old drunk. Guess the cops never found his glasses. I found this is the best way to kill a man. Best wishes, the Green Light Killa”

Police immediately started an investigation and gathered a large contingent of personnel to go out and search the railroad tracks through Gallatin.
The search included emergency management personnel, command staff, lieutenants, patrol officers, reserve officers and cadaver dogs but after searching “about a couple dozen miles of train tracks,” the team came up with nothing.

Police have considered the possibility of the postcard being a hoax.

Here is a scan of the postcard:

I can’t find any picture of the other side of the postcard on the internet.

Here is a handwriting comparison between Zodiac’s "Halloween card" and the "Green Light Killa card". See attachment…
