BARNSTABLE >> The attorney for a former Coast Guardsman from Virginia who's charged with killing a fellow Coast Guard member, then injuring her wife and a responding police officer in Massachusetts, says he plans an insanity defense.

The Cape Cod Times reports that Drew Segadelli, the attorney for Adrian Loya, said in court Wednesday an independent psychiatric evaluation found that Loya was unable to understand the wrongfulness of his actions.

Prosecutors say the 31-year-old Loya forced his way into a condominium in Bourne last February and killed Petty Officer Lisa Trubnikova and injured her wife, Petty Officer Anna Trubnikova, before shooting a responding officer.

Prosecutors plan to hire their own expert to evaluate Loya.

Loya has pleaded not guilty to murder and is being held in a state mental health facility.
