Is this the case that had a problem with the DNA evidence?

Chas.
I think so.

The judge threw out the DNA evidence. From what I read in the paper the lab technician ran the DNA through "old software" and did not get a match. They ran it a second time through "new software" and got a match. The lab technician admitted "proper procedures" were not followed. Whatever happened, the trial judge had doubts about the scientific reliability of the testing so threw the results out. Don't see that very often.

jury decided there was other sufficient physical evidence to convict the defendant so a guilty verdict was returned.

This is all based on what I read in the newspaper as I was not there.

Last month, presiding Judge David Wahlberg dismissed the majority of the DNA evidence in the case because of what he ruled were flawed analysis techniques used by a Texas Department of Public Safety forensic scientist. Prosecutors had planned to use this DNA to connect Criner to Weiser’s death.

Somebody messed up.

ETA:
That analyst, Jody Koehler, testified Tuesday that she did not follow the DPS’ multistep standard operating procedure when she changed her conclusion after running DNA samples through the software.

It was not clear exactly how Koehler erred, but it came out in her testimony that under the previous testing method, Criner would not have been found to match the DNA authorities found on Weiser’s right thigh. A radically different outcome resulted when she used the new software, which determined that it’s 192,000 times more likely that DNA found on Weiser’s thigh belonged to Weiser and Criner than to Weiser and anyone else.

Thanks ELB. I hope the Department of Public Safety can get its act together on DNA testing. I noticed that particular lab analyst is no longer with the DPS... Wonder what the difference was between the old software and the newer "STRMix" that was used to get a match. DNA testing been around for years and used in hundreds of criminal trials---something just does not smell right here.

I read the trial court threw out the DNA/testing. Wonder why? Do not see that very often.
