Ott is at the dry cleaners sometime in this period....DW's stuff is entered into the system sometime after DW left..she can't remember when she really did it....his clothes are assigned to some other person for a period of time...the printer doesn't work right, then it does....a blank receipt is given to the customer while the internal ones have all the info....Ott tells Torgerson it is Twin Peaks cuz he recognizes a receipt with NO info??
You may be right....Ott had opportunity and means...and he has a past of creating false evidence.
But why not plant something on DW for which there could be no explanation??..pj's in his house or a toy of hers or something??
