ROCKLAND — A Maine man accused of trying to kill his wife by hitting her over the head with a rock and pushing her off a cliff has asked a judge to dismiss the charges, claiming prosecutors improperly obtained his medical records.

Authorities say 69-year-old Charles Black tried to kill his wife in April 2011 by pushing her off Maiden Cliff on Mount Megunticook in Camden.

She fell a short way but survived.

Black has pleaded not guilty to charges including attempted murder and elevated aggravated assault.

The Bangor Daily News reports that his lawyer told a judge Wednesday that 540 pages of medical records were improperly obtained.

Prosecutors said only the investigator has seen the records.

Authorities have said money may have been the motive for the attempt.
