New DNA evidence guidelines could alter thousands of cases

TX AnalystDALLAS – Imagine you are on a jury, and are told that the suspect is the source of DNA found at a crime scene.
It’s a one-in-a-billion match.

It’s a question of math that is putting thousands of cases across Texas under the microscope, and could lead to convictions being overturned.
