They also showed the tweet about the cans of paint, so I think there will be more revealed about both.IMO
The hose and the paint, I believe we've heard the last of them. Cops can't prove what they were thinking, but given the circumstances of what was going on with Millard at that point in time, it is pretty easy for the jury to figure out what was going on. I believe they were going to spray the truck white prior to delivering it to the paint shop, and Millard was flooding his parking lot to remove evidence from where he washed down his truck or where he dumped ashes from the incinerator. Is the jury actually going to believe that after being involved in a murder, Millard was worried about a deck? Bottom line, both acts were likely something nefarious.
