Nearly one month after the attack on July 31st 1969, three letters were mailed to the San Francisco Chronicle, San Francisco Examiner and Vallejo Times-Herald threatening more murder and mayhem. Speculation inevitably arose after the Blue Rock Springs attack, as to whether Darlene Ferrin was specifically targeted by the killer, after three further suspicious phone calls were received in the early morning hours of July 5th. Much has been discussed regarding these phone calls, received at the 1300 Virginia Street residence of Darlene Ferrin, and the 930 Monterey Street residence of Mr Arthur J Ferrin and Mrs Mildred Ferrin at approximately 01:30 am, just one and a half hours after the murder of Darlene Ferrin and attempted murder of Michael Mageau at Blue Rock Springs.
Using the descriptors above, I went in search of a young male, heavyset, brownish hair, around 5'8", driving a vehicle similar or the same as the brown Corvair of Darlene Ferrin. This subject must also have had the ability to drive from Blue Rock Springs to a residence close to the payphone, so he could ditch his vehicle, weapon and clothing, and still walk to the payphone by 12:40 am and place the call to police dispatcher Nancy Slover. The murderer issued the message "I want to report a double murder. If you will go one mile east...... on Columbus Parkway to the public park, you will find the kids in a brown car. They were shot with a 9 mm Luger. I also killed those kids last year.... Good-bye". The wording of the killer gave the impression that he was unaware of the crime having already been discovered. Was he a resident close to the Vallejo Police Department and had not heard or seen the 'surge' of patrol cars heading along Solano Avenue to Springs Road?- which didn't happen. The answer to all the above observations already lay on page 42 of the Blue Rock Springs police report.
Patrick states that on 7-4-69 he went to the fireworks display at the waterfront and from there he went home. States that he parked his car in front of the house at 11:30 pm and did not leave after that time. Patrick's mother Delores was present and verified Patrick's statement. Patrick doesn't own a gun and he did not know Darlene Ferrin. Patrick states that the car can be started without a key but he is sure no one else used the car as it was in the same place in the morning as it was the night before. This car apparently has a bad oil leak as the street in front of the house showed oil on the pavement as though the car was leaking oil.
The similarities are likely unconnected, but 909 Georgia Street is the type of residence we should be looking for - if you buy into the notion of a killer walking to the payphone that morning. An approximate 10 minute drive home, 10 minutes to ditch the vehicle, weapon and clothes, before readying onself for the 15-20 minute journey to the payphone and placing the 12:40 am call to Nancy Slover. And... in a location to have not seen or heard the patrol cars leaving the Vallejo Police Department up Solano Avenue. This location (as the crow flies) is 400 meters from the Vallejo Police Department, 600 meters from Darlene Ferrin's residence, 400 meters from Solano Avenue, 500 meters from the old Vallejo Times-Herald office and 5/8 of a mile from the Springs and Tuolumne payphone. However, if the August 4th 1969 letter wasn't selling us one big red herring, then all of the above is superfluous.
