The linked report was written on 4/9 almost a month after the incident. It is noted as a supplemental, meaning to me he had written something else originally. How many reports / interviews had he written up since his 03/14 encounter with Kim at Kroger's. His recall level of details in the supplemental is interesting. If he had these details in his original notes, why would he have left them out of his report?
I find it odd (though it may be common practice) that all of the statements in the motion, Shelton's, Kim's and Jarriel's were modified some time after the original was submitted. Who is telling or suggesting to them that they modify their original writings..
He may have left them out originally because they didn't seem important at the time. That's normal.
