This would also support LE’s assertion that he was at the Spa business BEFORE heading home. He quit at 11 am, took MG home and then picked up hot tub stuff and THEN headed home. The Defence is saying (as per store owners) that he was there after 5 pm which is unlikely. Why go directly home and then go back into town later when he was already close by?
Or did he take her car back into town to get the chemicals? Remember the bottles were in her car.. seems so odd. Her car data wasn't back at the time of the AA being written.
