I know this was from the last thread, but I can't find it now. Someone had asked about whether the admin account would have been Deanna Reid because she'd bought it as a gift for Travis, and probably registered it (which is absolutely possible). But I was sure I'd seen a report, or someone who said that the computer was used, and the user logged in as Deanna Reid on June 4th - I couldn't find anything definitive at first, and thought maybe I'd misunderstood, but I did see it (no fog, phew).
I finally found it - on Day 12, testimony from Lonnie Dworkin (he was defense, not state) a forensic computer examiner, he says it toward the beginning of his testimony that someone logged in as Deanna Reid, and watched videos at around 4 in the morning.
Not sure if it's okay to post a link it this thread - so please delete (or tell me to if it's not) he starts at about 58:26 in.
