The first article was written before Paul Stine's murder was known to be a Zodiac killing.
The second article tells about the letter received by the Chronicle as well as more on Stine's murder. Of interest to me was that the article states the Stine letter was written with "pale blue ink". Honestly, I don't see that in the copies of the letter we know but what we don't know is what generation the copy is in the letter is that is online and how much it may have been darkened along the way.
