Submitting the Dear Boss envelope for DNA testing

[Astatine211]

Every time it was handled there's DNA left behind, it'll take them another hundred years to sort out all the DNA that'll be on it.

If there's DNA on the back of the stamp it should be an uncontaminated sample and it will be directly from the author when they licked it. Since DNA forensics weren't around in 1888 it's unlikely the sender of the letter would've worried about licking their own stamps.

Meh. Blowtorch and shrinkwrap.

Prolly used tar back then.

Luckily enough,King Richard III was not laminated back in 1485

It's hard to laminate a curved object.

You are wrong,again.

Thanks for yor deep insight.

With regards to the specific 'Dear Boss' envelope I was mistaken about it being that specific one that was tested under Cornwell's commissioned testing. She did however, conclude the lamination of the letter she tested had degraded any DNA traces. My guess is it will do the same for all the others too which were laminated.

If the envelope was laminated then de-laminated for the purposes if mDNA testing, there is every liklihood the DNA will be too degraded.

At best you prove person x posted the letter, as most believe the letters fake where does that leave us....

Don’t want the be a negative Nelly here but I am certain Patricia Cornwell tried the same thing and got nowhere. The chances of any usable DNA on this after such a long time is well, highly improbable.

[DJA]

Great idea.

No need to dig anyone up.

Family DNA matches should suffice.

Prolly worth leaving it until well after Easter when their workload is back to normal.

If you are looking for suspects,Thomas Openshaw took over as Curator of the London Hospital's Pathology Museum in 1887.
In that respect,he became the Boss of the previous curator.
Here is mikerscope of the previous curator .......

Currently the envelope for the Dear Boss letter is in the national archives. The envelope has a lilac one penny stamp on it and an envelope flap. Either behind the stamp or on the envelope flap could be the DNA of Jack the Ripper.

Submitting this envelope would be a simple way to make a potential breakthrough in the identity of JtR. Either if the DNA matched Fred Best or Thomas Bulling we would conclusively prove the name Jack the Ripper was a creation of the press.

This link gives great insight in how this envelope could provide us with answers and how the testing would be done: https://www.totheletterdna.com/envelopes-faqs

It's currently 5:45am but later I might contact the National Archives or the MET Archives and inquire if there would be any possibility of achieving this.

This shouldn't be difficult to do, nothing controversial like exhumation and would even involve the letter itself just the envelope. Yet this could also be one of the best bets of making a solid breakthrough in the case.
