The stab wounds (as explained in the previous analysis) to her left breast (2), right breast (1), right axillary fold (1) and right upper arm, grouped on an approximate 10cm vertical plane, is also consistent with an assailant holding the victim around the neck (possibly with their left arm) from behind, and stabbing backwards into the upper torso and upper right arm of Cheri Jo Bates, thereby resulting in the relatively close grouping of stab wounds to her frontal region. Her right arm being motioned across her body for protection would explain the two stab wounds to the upper right arm and right axillary fold. In fact, had she been stabbed here while using her right arm for protection over her chest, it would further narrow the horizontal plane width of the incoming knife. After thrusting Cheri Jo Bates to the driveway floor and kicking her in the head, the author of the Confession letter then claimed he "plunged the knife into her". This, too, is consistent with the one knife wound to her back detailed at autopsy. The word "plunged" maybe suggestive of a downward strike as she lay face down on the driveway floor, before he "finished the job out cutting her throat". The limited details given in the Confession letter are consistent with the previous analysis and the autopsy report, yet insufficient to fully claim that the author and murderer are one and the same.
