Here are 5 pieces of irrefutable, scientific evidence in this case, IMO.
I would be interested to hear arguments against all these pieces of evidence, that negate MTR's involvment in the crime whatsoever.
Please feel free to add to this list of evidence, as there are many other examples, but, I am limited by time.
Irrefutable Piece of Evidence #1:
Victoria's DNA places Victoria in MTR's car, without a doubt.
Irrefutable Piece of Evidence #2:
Victorias DNA was found deep within the inside of MTRs Gym Bag. MTRs blood was mixed in the very same spot, deep within the Gym Bag. The picture speaks for itself, IMO, that the chances the blood samples were put there at 2 different times are remote. Look at it!
Please note that the evidence indicates that the blood was found on the inner side of the stitching, where it was not exposed or visible. That is very telling, IMO.
Deep within the fabric of a gym bag found in his car, miniscule flakes of Michael Raffertys blood mingled with the blood flakes of Victoria Stafford

Irrefutable Piece of Evidence #3:
MTR's attempts to cover up his vehicle, one example of which, is the undeniable sanding of the whitewash on the passenger side door only, and the removal of the window crank, make a strong argument for a cover-up.
Irrefutable Piece of Evidence #4:
MTR lied and told LE that he did not know TLM very well.
Scientific evidence places both of them together in his car.
Irrefutable Piece of Evidence #5:
A small piece of cut upholstery was found in MTRs car, thereby corroborating TLMs testimony to cutting the seat.
