Believe me, when you sit on a gruesome murder case as a juror it takes a long time to get over it, and you never forget it fully. The images, whether of the crime scene or the discarded location of the victim showing the victim's body or skeletal remains or seeing them on the autopsy table it will remain with the jurors forever even if they try to push the memories aside. Yes, most likely they will have terrible nightmares. I know I did on both cases even before the trials had ended.
I have been a juror on two horrific murder cases. The third one I sat on was an assisted suicide done by the spouse of the man. One involved one victim and she was raped and murdered by a young 20 year old man who was her next door neighbor. It was a brutal rape and overkill. The other one was a death penalty case involving two young victims in their late 20s who were husband and wife. They were murdered by spree killers (3) who had come down in our area fleeing from the law in another state where they had killed another man for his vehicle. To this day I can see clearly all of their images in death, and I expect I always will. The cries, the anguish shown by their families in the courtroom does not go unnoticed by the jurors but we strictly looked at all the evidence only to come to our verdict.
Jurors will notice that ZAs grandfather sat down on Holly's side. Jurors are taking everything in that happens. They look closely at the witnesses' demeanor.
It has to be devastating for this jury to see the photo of such an alive beautiful vibrant young woman and then see her in death with so little remains being found for her family to even bury.
All of these jurors have families themselves with some having daughters, granddaughters or sisters Holly's age.
They also watch the defendant very closely and his reactions or non-reactions during the course of the trial.
Prayers for the jurors and justice for Holly!
