Maryland state Del. Don Dwyer was sentenced Tuesday to 30 days in jail for operating a boat while drunk during an August 2012 crash that injured seven people.

Dwyer, 55, pleaded guilty in Annapolis on Tuesday to operating his boat under the influence of alcohol, but District Judge Robert Wilcox denied his request for probation.

Wilcox told Dwyer he shouldn't get special treatment since lawmakers have an obligation to obey laws and ordered the Anne Arundel County Republican to also pay a $1,000 fine. He was facing up to a year behind bars.

Dwyer, 55, had a blood-alcohol content that was three times the legal limit for driving when his boat and another boat collided on the Magothy River near Pasadena, police said.

Dwyer apologized in court for operating his boat after drinking, but has maintained that the crash was not his fault.

The conviction does not require Dwyer to resign from the House of Delegates, his lawyer said.
