Police stop driver for speeding violation. Officer notes slurred speech, odor of alcohol and bloodshot/glassy eyes. Driver initially refuses to answer any questions but ultimately exits for field sobriety tests. Post arrest breath test of .20 excluded by defense. Prosecution is unable to go forward on four consecutive trial dates, despite repeated claims to Court that arresting officer has left department for federal job, but will return to testify at trial. Defense repeatedly demands trial or dismissal. OUI Charge dismissed for lack of prosecution.
