WALDOBORO, Maine — The Maine State Police arrested a Waldoboro woman Wednesday afternoon and charged her with murder in connection with the shooting death of her former boyfriend last month.

Detectives arrested Arline Seavey, 25, as she was being discharged from the Spring Harbor treatment center in Westbrook, according to Stephen McCausland, spokesman for the Maine Department of Public Safety.

Seavey, who also goes by the name of Arline Lawless, was transported to the Cumberland County Jail in Portland, where she is now being held.

Seavey is charged with fatally shooting 34-year-old Norman Benner of Waldoboro at the home she rented on Friendship Road in Waldoboro, state police reported.

Seavey suffered a self-inflicted gunshot wound to the face and has been treated for that injury since July 23, when Benner’s body was discovered by his relatives inside the home. Seavey was found wounded.

McCausland said Seavey and Benner had been seeing each other for a few months. He called the death a domestic violence homicide.

Seavey’s first court appearance likely will occur either Thursday or Friday in Lincoln County Superior Court in Wiscasset. More details on the investigation likely will be released at that time, McCausland said.
