The poem was predominately structured around the Roslyn Atwood attack, and was possibly written in blue ballpoint pen a matter of days after the November 3rd 1966 newspaper article. The Confession letter on November 29th 1966 likely continued where the desktop poem finished off, by describing that "next time". The Confession letter would contrast the fact that Roslyn Atwood was "unwilling to die" by remarking how Cheri Jo Bates "went to the slaughter like a lamb" and "went very willingly". The Confession letter also used the phrase "to die" again, stating "I said it was about time. She asked me "about time for what". I said it was about time for her to die". It must also be noted how the word "time" appeared 5 times in these two communications.
Roslyn Atwood attended night classes at the Riverside City College and had been attacked traveling home at 9:30pm that night, so it isn't beyond the realms of possibility that the desktop poem author attended the same night class as Roslyn, or had been at the Riverside college for other classes on April 13th 1965. Either way, if police could have confirmed she had bought such a dress and was wearing it when she was stabbed, it would have placed the author of the desktop poem extremely close to Roslyn Atwood at the Riverside City College. A college he would have been writing a desktop poem about 19 months later. For those who believe Zodiac to be responsible for the murder of Cheri Jo Bates, Roslyn Atwood could be the key.
