CHESAPEAKE BEACH, MARYLAND --- Calvert County Sheriff's deputies are combing the county looking for Graham Dale Buckmaster a man that Sheriff Mike Evans calls armed and dangerous following the murder of the man's longtime girlfriend on New Years Eve between 8 and 9 pm. The suspect in the murder is Chesapeake Beach restaurant owner and crabber Graham Dale Buckmaster, 57, who police believe shot Lisa Moore with a shotgun, killing her immediately. Moore is believed to have a daughter who lives in Calvert and had been living with Buckmaster in the couple's rented residence on Cox Road in Chesapeake Beach, where the murder took place. Sheriff Evans said that Moore had obtained an ex-parte which restricted Buckmaster from being near her or the residence and that an alleged violation of the order had taken place but had not yet been served on the man. Buckmaster's Seafood is an institution on the waterfront at Chesapeake Beach next to the Rod & Reel, between the bridge and adjoining the long line of charter boats.

Buckmaster allegedly ignored a court order to stay away from Lisa Moore, and forced his way into her Cheaspeake Beach home before shooting her.

Police are asking you to be on the lookout for a white, 2003 GMC pickup truck, with Maryland tags 85N235.
