Yes, that's what I said. The buccal swab was taken upon JLM's return to Virginia. It "seems" as though the wooden cigar tip was "taken" from him and tested upon his arrest in Texas as a preliminary step to matching his DNA to other evidence.
OT: Happy and safe Thanksgiving to all!
I agree that the cigar stub could have very well been taken after arrest. My only hesitation is that the warrant states that Charlottesville Police handed off the swab to the state lab, so I sense that they obtained the swab early on during the car and apartment search. I don't want to get too hung up on dates and over analysis; however, that excerpt from the leaked search warrant is bugging me, so I took one last stab and am walking away to focus on family and cranberry sauce. Happy Thanksgiving to you all!
Here's a little more from your link, which seems to explain that the cigar tip was not part of the leaked warrant:
"While we previously knew investigators had evidence that linked Matthew, who is also the suspect in the abduction of 18-year-old University of Virginia student Hannah Graham, to Harrington, the search warrant revelation is the first specific confirmation of that evidence.
There was a large diffuse of stain on the shirt, the search warrant indicated. A DNA mixture profile was developed
.on the shirt and searched against the Virginia DNA Data Bank. Search results indicated that the contributor of a foreign DNA profile, indicative of a male contributor, which was developed from a fingernail scraping of a female victim who was sexually assaulted by a male subject in a 2005 City of Fairfax, Virginia case, could not be eliminated as a contributor to the mixture profile taken from Harringtons shirt.
Matthew has recently been charged in connection to the 2005 sexual assault case.
Charlottesville Police then submitted a wooden tip from a cigar butt that Matthew had his wallet to the state crime lab.
A DNA profile was developed from the wooden tip from a cigar butt and could not be eliminated as a contributor to the sampling from the majority of the interior of the black t-shirt, the search warrant continued. The probability of randomly selecting an unrelated individual who would be included as a contributor to the DNA mixture profile is greater than one in 7.2 billion, which is approximately the world population.

Looked at this with fresh eyes. I had at first thought both of these analyses were completed recently. I now don't think that is the case; they were trying to establish probable cause to charge JM with murder and seeking evidence to support it like JM's phone records from 2009 at very least. They had no need to obtain a warrant for his DNA because they already knew that cigar tip matches the Fairfax perp DNA.
2010- DNA mixture profile was developed from diffuse stain on MH shirt.
Mixed DNA profile from shirt checked against VA DNAbank.
Contributor to shirt profile matched foreign DNA profile in Fairfax scraping
Conclusion: Fairfax suspect could not be eliminated as contributor to MH shirt profile.
2012- FBI updates sketch in Fairfax case.
2014- September 19-22 Time frame for taking cigar butt sample. Sample originates with Charlottesville Police, IMO.
Hit found with Fairfax profile.
2014- September 30 MH and JM linked via Fairfax evidence press reveals.
2014- October 8-15 DNA profile developed from wooden cigar butt taken from JM.
Could not be eliminated as a contributor to the majority of sampling over a broad area inside the shirt.
Could not eliminated as a contributor to the mixed DNA profiles on MH's shirt.
Probability that a non-related random matching profile contributed to the DNA mix on the shirt is 1 in 72 bilion.
2014 - October 24 Buccal swab analyzed in lab and matched to Fairfax perp.
My take away: Already known that cigar tip matches Fairfax perp, but it needs to match MH's shirt as common piece of evidence and to establish contact. I am thinking not only that, but it would be vital for the foreign DNA from both JM and Fairfax perp be located in same areas and in same concentrations on the shirt. This sounds like an obtuse thing to say, but I think there is a lot of random DNA interference from other people on the shirt.
