I thought Junes DNA was found ? how would that happen if all the blood had been cleared away and there had been no contact shot with June?
What part of "there was no blood left in the moderator after defense expert Lincoln removed the last traces in 1986" confuses you?
After his removal of blood, tests for any remaining prosecne of blood, including in 1999, came up negative.
That means the DNA found subsequent to this was not blood based. Tha tmeans such DNA was deposited from something other than blood.
The moderator was contaminated with June and Sheila's DNA by people handling items containing their DNA, getting their DNA on themselves and then transferring it to the moderator when they had the moderator apart. They no doubt transferred it to other items as well not just the moderator.
LNC DNA testing wa sinvented for use in identifying human remains. For all other applications one has to be very careful in what they try to assess from it because it can detect DNA that was innocently transferred.
So for instance a tiny speck of your DNA in the apartment of someone who you had contact with doesn't prove you were ever there period let alone there when such person was murdered.
If you had no prior contact with that person or anyone else who visited her who coudl have transferred it then in that case it would be evidence you were there yourself.
When contamination is ruled out as being possible that is when there is some significance.
If it is proved to be DNA from a specific source such as blood based or semen based then that also has implicaitons but that wa snot the case we know the DNA was not blood based so it had no probative value at all.
