Although the Kathleen Johns abduction occurred three years before the Klingels purchased the property in E Keyes Road and six years before the second purchase, the Zodiac Killer could have had family or friends, or had business dealings in Turlock or Hughson, that required him traveling there from the Bay Area before and after the Kathleen Johns abduction. If he had visited this area of California in 1970, he could have visited it regularly pre and post March 22nd 1970 - possibly into the 1980s and 1990s, where he may have crossed paths with Chester Clark Klingel in a personal or professional capacity. The route that Kathleen Johns took on March 22nd 1970 had her traveling northwest on Highway 99, through Turlock and near Hughson, California, before reaching Modesto and heading west on Highway 132. In fact, E Keyes Road passed over the top of Highway 99, with the 15-acre farm at 6413 E Keyes Road in Hughson situated less than two miles from Highway 99.
