Donna Lass lived at 4122 Balboa Street, San Francisco, just west of the Presidio, where she worked as a nurse at the Letterman General Hospital. It was the Presidio where Zodiac was seen entering just minutes after the murder of taxicab driver Paul Stine on October 11th 1969, never to be seen again. On June 5th 1970, Donna was preparing for her move to South Lake Tahoe to begin a new job at the Sahara Tahoe Hotel & Casino on June 6th 1970, temporarily moving in with Ann and Larry Lowe at 4054 US Highway 50, before taking up residence at the Monte Verdi apartments on 3893 Pioneer Trail Road. Exactly three months later, she would mysteriously disappear at the end of her shift on September 6th 1970. Her whereabouts have never been ascertained, but it is presumed she was murdered shortly after her abduction. Six months later, on March 22nd 1971, a postcard arrived at the San Francisco Chronicle containing a punch-hole and five pasted phrases - one of which stated "sought victim 12". Many have claimed this postcard was at the hands of a hoaxer because the victim total took a retrograde step, although it should be fairly obvious that somebody who was prepared to cut and paste this card, punch a hole and scallop the edges - who was equally determined to mimic the Zodiac Killer - would certainly have known the killer had already claimed 13, 14 and 17+ victims in his previous four communications. The past participle of the verb seek should have been the clue.
The sister card to the March 22nd 1971 offering, arrived on July 13th 1971 and was dubbed the Monticello Card. It was designed in similar fashion, stating "Near Monticello Shought Victims 21 ...... In The Woods Dies April". The author had once more used the past participle of the word seek, with the slight variation of "shought" - but was again suggesting that the victim had at one point in time been targeted. Kathy Bilek was being claimed by the Zodiac Killer, despite the fact that this murder had already been attributed to Karl Francis Werner. See here for details.
The Monticello Card was postmarked July 13th 1971 and Kathy Bilek was targeted and murdered in the Villa Montalvo woods in Saratoga on April 11th 1971. Therefore, a Zodiac Killer stating "shought victim 21", would be referring to a victim he targeted 94 days ago. In other words, he "shought" Kathy Bilek on April 11th 1971. This total of 21 would fit correctly in the Zodiac Killer sequence, because he claimed 17+ victims on March 13th 1971 when he mailed the Los Angeles letter. Let us apply this template of 94 days to the disappearance and murder of Donna Lass on September 6th 1970, to discover whether the "sought victim 12" would now fall into line with her being targeted in the Bay Area when she worked at the Letterman General Hospital.
If we deduct 94 days from the date of her disappearance on September 6th 1970, we get June 5th 1970 - the exact day she prepared for her move to South Lake Tahoe to begin work at the Sahara Tahoe Hotel & Casino. Was the Zodiac Killer effectively hinting that he had "sought" Donna Lass as victim number 12 in the Bay Area, but she had moved from San Francisco on June 5th or 6th 1970, thereby thwarting his plans? The April 20th 1970 '13 Symbol' cipher claimed 10 victims, which wasn't updated on the April 28th 1970 Dragon Card. The June 26th 1970 Button Letter had claimed 12 victims. Therefore, if Donna Lass had been "sought" as victim 12 by the Zodiac Killer, it would have fell somewhere between April 28th 1970 and June 5th 1970. Effectively, we are looking at the preceding month (May 1970) to when she packed up and left for South Lake Tahoe. This month could be pivotal in revealing the identity of the Zodiac Killer through the circles of Donna Ann Lass. Who were her close friends, colleagues or 'admirers' during this short window of time?
Through alliances with the Monticello Card, the Pines Card was almost certainly a Zodiac Killer offering - and therefore inconceivable that the phrase "sought victim 12" was simply a 'schoolby error' on behalf of the killer. Equally, a copycat with even the remnants of a brain, couldn't have made such a nonsensical mistake having made all the effort to mimic a Zodiac Killer communication in the first place. It wasn't like he was short of newspaper coverage. The retrograde step of the victim count to 12, in combination with the past tense of "sought" certainly wasn't a mistake - it was chosen for purpose. Possibly the day the Zodiac Killer's plans were scuppered as Donna Lass upped sticks and headed out of state to South Lake Tahoe.
