Conviction Integrity Unit
In the Bexar County District Attorney's Office, we have an independent unit called the Conviction Integrity Unit (CIU). The CIU handles all post-conviction reviews, writs of habeas corpus, Chapter 64 motions, and clemency and commutation petitions.
The mission of the Conviction Integrity Unit (CIU) is to conduct objective reviews of final convictions to determine whether there is some manifest injustice that may be corrected by the procedures provided by post-conviction law. This is accomplished through an open-door policy that allows for ongoing dialogue with members of the community, including defense attorneys, advocacy groups, and victims’ families. If we find a manifest injustice exists, we will address the issue and see that justice is achieved.
The CIU will consider any and all post-conviction claims that fall outside or subsequent to the direct appeal process. This includes, but is not limited to, formal filings for writs of habeas corpus, forensic testing, and clemency, as well as informal claims for equitable relief. The CIU accepts claims from any source, including innocence groups, members of the community, and otherwise. There is no claim that CIU will refuse to review or file a general denial of.
The CIU cannot re-open a case and investigate it as if it were a new case where no one has been convicted. However, the CIU will endeavor to review each and every claim with an open mind. The CIU will review cases in which there is new evidence, relevant evidence that went untested at the time of trial, or some other new evidence of innocence or that a person was convicted wrongfully.
This office cannot give legal advice to a defendant or a defendant's family members. However, the CIU can refer a case to the trial court for appointment of counsel where a manifest injustice requires it. The Conviction Integrity Unit also works with advocacy groups such as the Innocence Project to facilitate discovery and help navigate post-conviction relief in Bexar County. If you are a member of an advocacy group with an interest in a Bexar County case, please feel free to contact the CIU at CIU@bexar.org regarding your case.

CASE REVIEW FORM
Please fill out the form below as completely as possible. Once it is complete, please mail the form to the address listed on the document. The more proof you can offer that a conviction was wrongful, the more likely we are to review the case. If you can provide documents that support your claims, that will be helpful too.

HAVEN FOR HOPE AND THE SECOND CHANCE FOR SUCCESS PROGRAM
In September of 2021, following the exoneration of Devin Lamar Lynn, the Conviction Integrity Unit has partnered with Haven for Hope to launch the “Second Chance for Success” program. This internal review project is centered on a review of Haven for Hope’s homeless clients’ convictions for potential post-conviction relief. Haven for Hope clients seeking assistance from the CIU should fill out the online intake form and submit it to CIU@bexar.org for review.
POST-CONVICTION DRUG REVIEW AND Bad Confidential Informants
The Conviction Integrity Unit reviews post-adjudication controlled substances cases to ensure that the substance in question was accurately examined and tested.
The CIU has investigated cases based on false information provided by a confidential informant. The unit has identified at least three affected post-conviction cases. Information was also provided to prosecutors on pending cases, as well as to law enforcement agencies to stop the use of this informant. If you suspect your case was adversely affected by a confidential informant, please contact the CIU at CIU@bexar.org.
