Hi guys,
Students of an university found out (through rumours and tales from ex-students) about an underground tunnelsystem below the university. Some guys entered the system and came to a place called "the beach", a huge area with lots of sand in it. Near a ladder going to the surface they found a coded message. It ends with plain English text saying "forgive me".
In the attachment you can see the mysterious message
Some of the capital letters reminded me of the capital letters used in the "Bates Had to Die" letters. It could be coincidence ofc.
The words "forgive me" looks like Zodiac’s handwriting style but could be coincidence as well…

This was the underground area this message was found in. The students thought there could have been something buried there but never digged because they were afraid of being caught by the campus security.
Here is another photo of this secret underground area.
Doesn’t look "secret", but rather "normally not accessible to students". Looks well maintained and in use, probably by Facilities and Operations. As for the message, it looks quite recently written. Do we know which university this is? When the images were captured? What is the connection with Z?
TheMist,
You are right, not really secret. I found newsarticles about the underground system from 1956 and 1969. The images I sent were screencaptures from a documentary I saw that was made in 2005. The photo’s they showed in it were a few years older. So the message is not recent. Btw the University is the University of Texas…
