They have evidence from her computer so like she said in her interviews, she accepts it if the evidence says so, but can’t say why she did. She can’t really deny it if there is concrete evidence like that. It would be a clear lie if she denied it.
Just speculation but perhaps she handled the stressful shifts by having a drink afterwards. There’s the possibility that she looked them up online under the influence but didn’t remember it the next day, so perhaps when police presented this evidence to her, she couldn’t deny it but genuinely couldn’t remember if she had done it .
Not saying she’s a raging alcoholic but high stress environments in healthcare, especially with shift work, make sleeping very tough and I know a lot of people who rely on self-medicating to be able to sleep.
I myself have been known to have a couple drinks after a long day, especially if I have the next day off work. I’ve never done anything dodgy but if the police came up to me 2-3 years after the fact and asked if I’d remembered searching for someone online, I probably would also claim I didn’t remember it!
For what it’s worth, I’m leading towards guilty but mostly undecided.
I am glad this case is going through a full trial to examine all of the evidence.
