I expect the jurors have been excused future jury service, and hope they have received professional help.Just imagine being a member of the jury and having to sit through all of it without being able turn it off or tune out. It must have been horrifying.
Ex father-in-law was traumatised by being a juror on a horrible rape case in the 1960s. He still had nightmares about it when I first met him in the 80s. But he didn't have to serve on another case.
