Mr. Phillips served 12 years in prison and then had to register as a sex offender after his release. As a result of not complying with the registration requirements he eventually went back to jail for another six months.
Earlier this year the DNA evidence in that rape case was tested - but not at Mr. Phillips' request. The kit was tested at the behest of the Dallas County DA's Office. The results of that test exonerated Mr. Phillips.
But why was the DA's Office testing a rape kit that had set on a shelf for more than two decades? Why were they testing a rape kit when the man convicted of the crime didn't request it?
Dallas County DA Craig Watkins would like you to believe that this was an incident in which his Conviction Integrity Unit was doing its job in making certain that no one was convicted of a crime they didn't commit. But that's not the reason the rape kit was tested.
You see Dallas County has a serious problem with its crime lab. Forensic work in Dallas County is performed by the Southwest Institute of Forensic Sciences. And SWIFS doesn't have a particularly good track record when it comes to DNA testing.
I have linked to a copy of an audit performed by the US Department of Justice in 2009 that paints a very disturbing picture of the crime lab.
Here is an excerpt from the report on the lab's compliance with CODIS protocols in the DNA section:
In our sample of 103 profiles, 2 profiles were inaccurate and 18 profiles were deleted from NDIS because they were unallowable, incomplete, or missing, and because of insufficient record retention, 15 of the Laboratory's files did not have sufficient evidence to determine if the profiles were obtained from a crime scene. The Laboratory deleted these 35 profiles from NDIS. The remaining 68 profiles we reviewed were complete, accurate, and allowable for inclusion in NDIS. However, 58 of the 103 profiles in our sample are not searchable at NDIS because they contain 9 or less core loci rather than the minimum of 10 loci required to be searchable at NDIS.4 Prior to January 2009, the Laboratory only attempted the analysis of 13 loci on forensic samples that did not have a standard for comparison, but in January 2009, the Laboratory began attempting the analysis of 13 core loci. However, 11 (30 percent) of the 37 samples analyzed between January 1, 2009, and May 13, 2009, contained less than 13 loci. The CODlS Administrator explained that it could be a matter of timing if the profile was run prior to January 1, 2009, or 13 loci were not run either because a suspect profile had already been developed for comparison or some of the sample was preserved for later use.If this is the best that SWIFS can do, then Dallas County is in serious trouble. This, unfortunately, seems to be par for the course for crime labs run by and for law enforcement. These labs aren't meant to be independent. They are meant to generate evidence that the state can use against those accused of criminal acts. This mission encourages sloppiness and it encourages analysts to err on the side of law enforcement when making close calls.
The system is broken and it can't be fixed.
