Police in Tallahassee, Florida were on high alert after a message appeared on a sidewalk that looked very similar to the writing and cryptograms written by the Zodiac serial killer in the late 1960s and early 1970s in Northern California. The Zodiac Killer's identity is still unknown. Here's the message:
You were wrong. I am not dead or in the hospital. Im alive and well and Im going to start killing again."
Turns out, the message was part of an assignment on serial killers and drug cartels in a Florida State University class. According to the Tallahassee Democrat, "the assignment was to write a message in a public forum, take a picture and send it to (professor Iheoma) Nwachukwu.
