Ah, thank you! MY memory retains odd bits and pieces sometimes. I will remember the name Michael Douglass now (unfortunately, an easy one to remember from this point onwards given the actor ...wonder if fbi SA Douglass added the second 's' deliberately ;-) ).
In addition to the American Expresss records, there are several others, though not sure if Mr two ess Douglass is mentioned in person again. After Mowery (in most cases) states " I received the requested information", there is in these instances a line following that states he emailed it to ...blank...which I remember surmising at the time was probably a digital forensic specialist. I think occasionally, some of the delays in loading the return inventory into evidence may have been due to awaiting fbi analysis of data. Or Mowery receives the inventory from the fbi (who has received it directly from the warranted body) and then downloads. MOO and educated guessing.
