I'm not sure how exhibits are stored. I would think all exhibits are stored in a correct way as to not contaminate in there relevant packaging. I wouldn't think that all the nightware would have all been stored in one bag....
They would use a different method of DNA profiling and probably not the LCN... I'm not sure the jurors did handle the exhibits without them being protected? Maybe NGB can tell us....
If exhibits are not stored correctly then what happens in a cold case?

Hi Patti
See your post #178. LCN DNA was not even envisaged '85/'86 so the necessary precautions to prevent contamination would not have been taken.
Jurors were told to wear gloves but I believe this was for their own protection rather than protection of exhibits.
Maybe there are less sensitive ways of DNA profiling than LCN which might yield results. I believe LCN was used with silencer as the blood had been swabbed to death in '85/'86 for standard blood groupings.
Just think even if EP hadn't destroyed other exhibits defence and prosecution would have claimed contamination.
