19 year old client was arrested after travelling the wrong way on a one way street in Worcester. Officers removed him from the vehicle and asked him to perform field sobriety tests. Due to failing the tests and admitting to consuming pills, he was charged with OUI-Drugs among other motor vehicle charges. After attacking the credibility of the evidence and the credentials of the proposed drug expert, we were able to get the charge of OUI-Drugs dismissed prior to trial.
