ORCHARD OF DEATH - Two sheriff's detectives stand on each side of the 24th victims grave found today in an area that was under irrigation water on the edge of the Sullivan Ranch. The white paper bags in front of the grave once contained the surgical gloves the diggers wear when they remove the body. The furrows are an irrigation check found in the orchard during the spring and summer months. In this case the grave was located on the exact crossing.
