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.
How the killer approached is open to question, but the assailant unleashed a barrage of gunfire into their car blowing in both front side windows, testimony to this was the 15 small caliber shell casings scattered and retrieved from around the car. The couple suffered multiple shots to the head.
Sacramento is situated approximately one hours drive North-East from Vallejo CA and one hour and forty minutes due East of Lake Berryessa, and mentioned in two letters by the Zodiac Killer. Firstly, in the dubious Fairfield Letter postmarked December 16th 1969, it was claimed by the author he would go on to kill at least 38 more people, including three in Fairfield, CA and nine in Sacramento. Fairfield is on a direct route from Vallejo through to Sacramento and within easy traveling distance for the Zodiac Killer, if indeed he was a resident of the Benicia, Vallejo or San Francisco area at the said time period.
More crucially though, the 1986 Letter, mailed on Tuesday May 6th, is relevant to the date and area where Koy Ien Saechao and Choy Fow Salee were gunned down.
As stated in a previous post on this topic, he claimed in the 1986 Letter that these latest victims were killed ''about two weeks ago''.
Exactly two weeks prior to May 6th would have been April 22nd 1986, the exact date of the cold blooded murder of Koy Ien Saechao and Choy Fow Salee.
The method of execution here is eerily familiar to that of the Lake Herman Road double murder of David Faraday and Betty Lou Jensen on December 20th 1968 and the Blue Rock Springs Park murder and attempted murder of Darlene Ferrin and Michael Mageau on July 4th 1969. All couples ambushed in their car, and although not substantiated, it may be likely the killer approached this couple from behind in his vehicle, due to the locality of the crime.
The most interesting aspect of the Laotian couples murder though, was that shortly afterwards a 'Mystery Man', thought to be a 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. He was later sought for questioning in connection to the double murder on Highway 99 but he failed to come forward, and his identity remains unknown to this day.
The author of the 1986 Letter stated "I will give you a clue to help you with the mystry, They were killed by a freeway. The Blue Meannies almost caught me". Had the murderer already given the clue about his own identity to the California Highway Patrol Officer and he indeed was the 'Mystry' Man.
A relative of Koy Ien Saechao and Choy Fow Salee said "We don't want to get killed in the United States, we want to live here for freedom". Let us hope one day they find a resolution to the answers they desperately yearn, and the killer, whomever they may be, finds that freedom will one day be no more.
