Paradise Point is 44 miles from the Carquinez Bridge (and Interstate 80) which runs from Vallejo to Crockett, and about 10 miles from Lodi, California. The San Joaquin River flows west from the high elevations of the Sierra Nevada Range to the valley floor and then heads north to Vernalis where it flows into the Delta. The area where the bottle was discovered is punctuated by the White Slough Wildlife Area - 880 acres of man-made ditches, canals, freshwater marshes and grassland. It is highly improbable a bottle dropped into the water by Vallejo would find itself here three months later, and every chance the bottle was thrown or placed into the water in the vicinity of where it was found, or east of this location.
The author of this note can easily mimic previous Zodiac communications, so very little can be done to prove its authenticity or otherwise. The phraseology of "please help me" is identical to the wording on the Melvin Belli Letter mailed on December 20th 1969, and similar to the "I just need help" on the December 7th 1969 Fairfield Letter. To give some form of timeline to this communication - it was likely placed into the water six months prior to the Albany Times Union Letter mailed on August 1st 1973, stating "You were wrong, I am not dead. I am alive and well and I'm going to start killing again".
There would be a devastating number of murders in Lodi, California that year (10 miles from Paradise Point) when on November 9th 1973 Willie L. Steelman (28) and Douglas E. Gretzler (22) were arrested for the massacre of nine people in a family home. Walter Parkin, his wife and two children, along with five friends had been bound and shot in the head.
