Rewinding the clock back fifteen years, the Donna Lass case entered the Zodiac sphere with the mailing of the Pines Card on March 22nd 1971 inferring he may be the killer. Donna Lass disappeared from a South Lake Tahoe casino in the early hours of September 6th 1970 and has never been heard or seen of since.
Gian Quaser of the Quester Files ran a story indicating a possible link between Donna Lass, Judith Hakari, Nancy Bennalack and Carol Hilburn, the latter three of which were all murdered in Sacramento in 1970. A straight line from the Vallejo and San Francisco region to South Lake Tahoe takes you directly through Sacramento. The slaying of Koy Ien Saechao and Choy Fow Saelee, although sixteen years later, took place within 10 miles of the murdered women in Sacramento, and furthermore the Zodiac Killer would possibly claim these murders in a 1986 letter.. What is most important, is what the Zodiac meant in the 1986 letter by "The Blue Meannies almost caught me." Is he talking about his interaction with the Highway Patrol officer in the article.
Koy Ien Saechao and Choy Fow Saelee were traveling back on the two and a half journey to their residence in Dorman Road, Yuba City after visiting their son in a Merced CA hospital, situated in the area of the San Joaquin Valley of Northern California. They were only 45 minutes from home when it was believed they had opted to take a rest on the roadside edge, near the interchange of Highway 99 and I-5 Sacramento and unfortunately for them, a merciless killer was in the vicinity. However, without knowing the exact dynamics of the crime, it is equally plausible they were ushered to the side of the highway on a ruse similar to the Modesto abduction of Kathleen Johns.
The 1986 letter claimed to be from the Bay Area killer, but what catches the eye, is how close this letter is to the Koy Ien Saechao and Choy Fow Saelee murders.
 The letter was postmarked 6th May 1986. The letter writer stated his victims were collected "about two weeks ago". Exactly 14 days prior to May 6th was April 22nd, the day the couple were murdered.
 The letter writer stated "up by Sacramento". They were murdered close to the center of Sacramento.
 The letter writer stated "They were killed by a freeway" and "I want you to know about my latest slaves". Both statements indicative of more than one victim. The couple were also murdered right next to a two lane freeway. (Highway 99).
This Highway serves Modesto and was traveled by Kathleen Johns in March 1970. Wikipedia: 'From SR 99 to south of Tracy, I-5 skirts along the far more remote western edge of the great Central Valley, and thus here is removed from population centers such as Bakersfield and Fresno; other state highways provide these connections. I-580 splits from I-5 at a point south of Tracy, providing a loop-route connection to the San Francisco Bay Area. After passing Tracy, I-5 heads north through Stockton and Sacramento before turning west to Woodland.'
 The letter writer stated "The Blue Meannies almost caught me," indicating that he saw police that night, likely close to the scene. The mystery hitchhiker directed police to the scene, reminiscent of his two phone calls, but subsequently was never traced. Was this the Zodiac playing games with the police and hence his reference to "The Blue Meannies almost caught me". The hitchhiker flagged down a California Highway Patrol Officer in East Nicolaus and informed him of an automobile accident at the precise location the couple were eventually discovered.
The Zodiac could again be claiming murders for which he had no hand in, so it is imperative to find more detailed information on this crime and possibly elaborate on his claim of a near miss with police. It would also be interesting to discover the weapon used in this crime and compare the shell casings to ones retrieved in the Zodiac case.
