METHUEN, Mass. (AP) _ A respected plastic surgeon was accused of shooting his estranged wife's boyfriend to death during a visit to the wife's hospital room.

Dr. James Kartell, a 25-year veteran of Holy Family Hospital, went to see his wife, Suzan Kamm, in the hospital Tuesday. Police said he encountered 56-year-old Janos Vajda, who was believed to be the wife's new boyfriend.

An argument between the two men followed, and Kartell allegedly shot Vajda in the head.

Kartell, 59, was treated in the Holy Family emergency room for minor injuries. Kartell, who has a history of heart problems, was later admitted to the cardiac care unit, police said. District Attorney Kevin Burke said Kartell would be arraigned today in his hospital bed.

Ms. Kamm, a psychologist, remained under a doctor's care at the hospital. Her condition would not be released, said hospital president William Lane, a longtime friend of Kartell.

``I didn't see it coming,'' said Lane, who added that Kartell was so well-liked by his peers that they twice elected him president of the hospital's medical staff.
