How taking a home genetics test could help catch a murderer
How taking a home genetics test could help catch a murderer

So they got the Golden State Killer, next they got William Earl Talbott II, could the owner of the dna found on JonBenet be identified using the same method?

.
The short answer is no. There is no full profile to work with. The shady, shoddy sample they have, is just that. It was designed to stay in CODIS forever and never get a hit.

During Lacy’s last ditch effort to exonerate the family with the 2008 round of DNA tests, lab techs were unable to replicate the same DNA profile in her underwear that was found in 1997 testing.

Cottonstar,
OK, I thought a digital version of the DNA profile might be linked to some family grouping, e.g. asian?

nah the investigation was sloppy dna is messy and most like come back inconclusive

JonBenet's killer is in Patsy's grave. DNA Does Not Apply.

The case is so complex I forgot about this:

Kolar's Reddit AMA Interview, excerpt
• Question:
1. Are you aware that Pam Paugh made note of several things to police who escorted her into the house when she went to pick up items for the family and the funeral? She pointed out specific information about JonBenet's bedroom door and a chandelier that appeared different from normal. The police made no note of this very valid information.

2. Has the Boulder PD ever considered using familial DNA to enter a partial (most identifiable markers) sample of the DNA profile into CODIS to see if they can find a relative to match the profile DNA? This method has solved many cases in the UK and it's legal in Colorado. Also there is a DNA technique where they can determine genetic defects of the profile, eye color, ethnicity, hair color, etc. This would certainly narrow down the owner of the DNA profile. And even though you do not believe it belongs to the killer they might find the owner and be able to find the owner and possibly eliminate it to move forward.

Answer:
The only DNA sample of sufficient quality to compare with anyone is the degraded unknown sample identified as Distal Stan 007-2, which consists of 10 markers out of 13 for a full profile. It is compared on a weekly basis to any new DNA submissions made through the arrest of new offenders. It is also compared against any new unknown DNA samples entered into the unidentified forensic files maintained by state and federal authorities.

If a partial match was ever identified through a familial sample in the system, I would presume that authorities would take a closer look for a possible match.
I believe a firm in Florida has been experimenting with genetic profiling, but it has been quite some time since I looked into those capabilities and I don’t know if this testing has been considered by authorities.
