On a jury, you focus on exactly what the judge tells you and nothing else. Most jurors take their job extremely seriously. I've been a panel member on several cases - murder, major fraud, drugs possession/dealing, illegal use of a car,
With a complicated time line such as this case, and the disjointed sequence of events as they are presented by the various witnesses, do the jury create or draw up a detailed timeline of events and pieces from the witness testimonies? I have never been on a jury, but it would be something I think would be necessary as an agreed basis for the jury deliberations by first going through all he testimony and opening/closing address transcripts to build this timeline up.
I know that the prosecution (and maybe the defence) would probably go through a sequencing of events and also joining some of the dots (eg the death cap mushroom photo that an expert was asked to identify was the same phot that the digital expert later shoed was from Erin's tablet), during their closing address, but I don't imagine it would be complete or detailed enough.
