Warning This Section Does Contain Spoilers For Solving The Cyphers For Episode Six
The Pen Pal letter from JWJ has a cypher hidden in the text. Using the code from the coded lock of 413, and also the letters from the bottom of the LFoA Letter, we find the message "I Killed Heather".
The coded lock reflects the bible verse fro 1 Thessalonians 4:13. Taking all the numbers from the bottom of the LFoA letter that coincide with the numbers 4, 1, and 3 we have the letters: A, D, E, H, I, K, L, R, T,
When circling all the letters in the JWJ letter we can find our message in the last paragraph. The word Heather is broken and interrupted by the letters "died" for a complete message of:
"he died ather I killed" - "Heather I Killed" - "I Killed Heather".
So far we assume JWJ has killed George Madson. We suspect he might have had something to do with Lloyd's death, or at the very least, Lloyd's death was suspicious. But he has now openly admitted to killing Heather, a woman.
