An Instagram user by the name of “darkprince4564” had purchased one of Ramirez’s prison owned books.
They noted that this must have been the main book he used as a “desk” to write all his letters. As you can see, there are markings on the book, even of his signature ! They even noticed words and even smiley faces on the cover.
The original poster also pointed out that as they looked through the book, they noticed that Ramirez actually cut out all of the religious symbols that include crosses, they even looked up the original photos and put them side to side.
(If anyone decides to post this or any other post I have in general on another platform, pls give credit !)
