HOUSTON -- The Houston Police Department
used to perform the majority of its forensic DNA testing in its own crime laboratory. The department ceased operation of its DNA analysis unit after investigations revealed that it had failed to maintain certain standards needed to ensure the accuracy of its DNA testing.
The department will now use Orchid Cellmark to conduct forensic DNA analysis for new cases as well as retesting for prior cases. The company's laboratories are certified by the American Association of Blood Banks.
