According to the Travis Country Distric Attorney’s Office, hundreds of DNA samples may need retesting, due to scientific concern over the interpretation of DNA results and issues with a DNA statistics database.
This may impact some criminal cases as the chances a suspect’s DNA is at a crime scene might be calculated differently in light of the new guidelines on how DNA should be analysed.
The exact number of cases that would need to be reviewed is unknown at the time. In a large undertaking, the District Attorney’s Office is working to identify and address these cases now.
