The Sorrento Italian Restaurant was located at 9844 Magnolia Avenue. La Sierra University was located at 4500 Riverwalk Parkway, one mile north of Magnolia Avenue, with the Riverside City College at 4800 Magnolia Ave. The Italian restaurant just 2.5 miles from the grounds of La Sierra University. Tom Voigt makes an interesting connection to the November 29th 1966 'Confession' letter in which the author concludes "I am not sick. I am insane. But that will not stop the game", and reminiscent of the "dangerous game" he played out in the Bay Area. Tom Voigt hypothesised on whether there may have been an element of truth in the author's frankness, deducing that the only psychiatric facility available in 1966 was the Riverside General Hospital University Medical Center (founded 1893) and located at 9851 Magnolia Avenue, virtually on the doorstep of the Sorrento Italian Restaurant. Tom Voigt concluded that if the Zodiac Killer was responsible for the murder of Cheri Jo Bates and received any treatment for a mental illness, then it's perfectly conceivable he received this treatment across the road from the Sorrento Restaurant - and may have visited the restaurant himself. Placing two victims and the Zodiac Killer in the same room would obviously turn the search for the infamous Bay Area murderer on its head, albeit layered with a degree of cautious optimism.
