MINEOLA - The investigation into the embattled Nassau County Crime Lab has uncovered additional mix-ups in the test results of at least nine DWI cases.

Prosecutors say that paperwork in the misdemeanor drunken-driving cases was mishandled by the lab on Oct. 15 of last year. They say results showed some drivers who didn't have alcohol in their system were charged with DWI, while others who had been drinking showed a blood-alcohol level of zero.

According to defense attorney Brian Griffin, he has learned of another case where the lab over-reported the testing of alcohol on a different date. Officials now say they're questioning how many cases from the past four or five years have been prosecuted with faulty blood results.

The lab has been shut down since last month, when the mistakes were first uncovered.
