The state dropped Thursday an operating under the influence charge against a Rockland fire lieutenant.

Dennis R. Camber, 53, of South Thomaston, had been arrested on the night of Sept. 11 in Thomaston.

Assistant District Attorney Jeffrey Baroody said Dec. 21 that the decision to dismiss the OUI charge was based on the realization that the defense would have been able to provide reasonable doubt if the case had gone to trial.

Camber was arrested after being found in his car, which was parked in the parking lot of the Hampton Inn & Suites. He had been drinking at the adjacent Applebee's restaurant, Baroody said.

The defense had an expert witness who would have raised doubt about the estimated blood alcohol level of Camber when he drove the short distance to the parking space.

He was not driving when the police officer arrived.

The district attorney's office had stated it would request jail time if Camber was convicted. He had an OUI conviction from July 2011 in West Bath District Court, according to the criminal complaint filed earlier in the year in Knox County by the district attorney's office.

Rockland City Manager Tom Luttrell said Camber has taken some vacation and personal time and has not worked since the arrest but that he is not on administrative leave. He said Dec. 21 he would be meeting with Camber after Christmas.
