BCA ~ I find it interesting in Dedering's
11/03/16 report of his meeting with Zipperers that he mentions the voice mail Caller ID-time to Zipperer at 2:12 pm, then he continues and writes that Teresa states (at 2:15 pm) that she "...will be there in a few minutes." Consequently, it appears as if Teresa places herself at Zipperers sometime "within minutes" shortly before then going to Avery's.
Whatever confusion is in Jolleen's mind about Teresa's time of arrival is much clearer when we simply accept Teresa in her own words.
With regard to Dedering's report...I have little reason to believe that he would fudge the two times, as it would take a very, quick-thinking, devious mind to put two-and-two together and begin a conspiracy right then and there on Nov. 3.
