According to the obituary of Chester Clark Klingel, it somewhat detailed his timeline. The obituary read "Chet's first wife Yolanda passed away in a car accident. His second marriage was short but his third to Blandina Sarkis added love, happiness, family and great food to his life. He had many good years in Tam Valley, CA, before beginning a farming venture near Turlock, CA. Chet and Blandina bought nut orchards and developed a successful walnut hulling and drying business. After Blandina passed away, the farming project lost appeal. Chet sold the farm and moved to Eureka, CA, where he made new friends". The problem we have, is that the obituary stated that Chester Clark Klingel moved to Eureka after Blandina Sarkis Klingel died. She died on September 9th 1993 (aged 63). Therefore, if the obituary is accurate, Chester Clark Klingel moved to Eureka subsequent to her death in September 1993. So what was he doing with a post office box in Eureka when he didn't live there in 1990? Blandina Sarkis Klingel was buried in Turlock Memorial Park, Turlock, Stanislaus County, which is 370 miles from Eureka.
'The Foreigner', a contributor to the Zodiac Killer Site forum, did point out that Chester Clark Klingel's daughter was living in Eureka at the time the Eureka card was mailed. However, If the claim we have been led to believe for many years is correct, that Chester Clark Klingel had been living in Eureka in 1990 with his wife Blandina, it would be unusual for her to be buried in Turlock, Ca, which is a 740 mile round trip for her husband. This story requires more explanation, because something doesn't make sense.
