According to the Confession letter, the distributor of Cheri Jo Bates' green Volkswagen Beetle had been tampered with in the pretext to offering her assistance, when apparently the only objective of the good Samaritan was to lure the young girl to her death.
In the latter half of 1968 in Telegraph Avenue, Berkeley, two girls were offered a lift by a brown-haired man, estimated to be about 30 to 40 years of age. Despite the young women politely declining his offer, indicating their Volkswagen was parked up on the nearby avenue, it appeared he was more than determined to lure the girls into his vehicle. After declining his offer they proceeded to a local snack bar, where they remained chatting for approximately 45 minutes. After leaving the snack bar they headed back to their vehicle only to discover they were unable to start the Volkswagen, when the man they had encountered earlier promptly reappeared to offer his assistance once more. The man helped the girls push their vehicle along the road, when a second man came along to assist in their plight, however, this only seemed to infuriate the initial 'good Samaritan', who then, apparently annoyed by a perceived intrusion from the other gentleman, got back in his car and made a hasty exit from the scene. Some time later it was discovered that their car had been tampered with - the distributor cap having been torn from the engine, similar in fashion to Cheri Jo Bates' Volkswagen Beetle.
The Zodiac Killer seemed annoyed and frustrated when his letters never received front page coverage, or the attention he so clearly craved as an individual, often surfacing throughout his correspondence with the newspapers in the Bay Area. Did this apparent frustration surface again four years after the Telegraph Avenue incident, on April 7th 1972, when a further offer of assistance was once again spurned? Isobel Watson (33) had just got off the bus on the evening of April 7th 1972, and was walking home along Pine Hill Road, Tamalpais Valley, Marin County at 9:00 pm, when a light-colored vehicle veered towards her, knocking her to the ground. [view on google maps] The driver exited his vehicle offering her assistance and his willingness to take her home, but after she had refused his offer of apparent help a second time, the concerned citizen suddenly became enraged, pulling out a knife and stabbing the woman in the neck and shoulder. Her screams alerted the neighborhood, forcing the assailant into a hasty retreat from the scene. See Tamalpais Valley Attack.
