Texas Post-Conviction DNA Testing A Legal Guide to Chapter 64 of the Texas Code of Criminal Procedure By Andrew Kizer DNA evidence has become one of the most powerful tools for exposing wrongful convictions . Yet in Texas, obtaining post-conviction DNA testing is far more complex than many people realize. Texas Post-Conviction DNA Testing: A Legal and Practical Guide to Chapter 64 provides a clear and comprehensive explanation of the Texas law that governs requests for DNA testing after conviction. This statute— Chapter 64 of the Texas Code of Criminal Procedure —has helped free innocent people, but it also contains procedural barriers that often prevent courts from reviewing potentially exculpatory evidence. Written by incarcerated legal researcher Andrew Kizer , this book explains how the law operates in real cases and how it has been interpreted by Texas courts. The guide translates complex legal doctrine into understandable language while offering practical insight into how DNA evidence can be used to challenge wrongful convictions.
