This could be a nice start for finding a different solution for the Donna Lass poster cipher:
It could also be ‘talk in wood’ or ‘good’ etc..but the connection to wood might be a good one.
‘_ _ _ A _ _ I AM STALE IN WOOD…DONNA LASS’

There’s nothing to find, this was actually put out by some of Donna Lass’s family and the police department. I’ve read, so wouldn’t waste time on this cipher like they did in the show.
We don’t know if the cipher is based on an unknown letter or simply made up (for fun?) by Donna Lass’ relatives, do we?

Unknown letter? To/from whom?
It was not created by Zodiac, but have it at. 
“…they may be dealing with one or more ersatz Zodiacs–other psychotics eager to get into the act, or perhaps even other murderers eager to lay their crimes at the real Zodiac’s doorstep.“ L.A. Times, 1969
