A recently dismissed Harvard dermatologist was arraigned this week for allegedly killing his estranged wife at her Wenham home last Friday night.

Dr. Richard J. Sharpe, a member of the Harvard Medical School faculty for over a decade until he was dismissed last month for neglecting his duties, is awaiting indictment after police arrested him early Sunday morning following a siege at a New Hampshire motel.

Wenham police found the body of Karen Sharpe in the front hall of her home Friday night following a 911 emergency call. She was rushed to Beverly Hospital, where she was pronounced dead from a single gunshot to the chest.

The couple was divorcing after a 27-year marriage, and Sharpe's wife had obtained a restraining order against him.

According to Wenham police Lieutenant James Foley, a tip from a motel owner in rural Tuftonboro, N.H., who had seen Sharpe's photo on the Saturday evening news, led police to the suspect.

Sharpe had come to the motel asking to rent a room, but the clerk referred him to a nearby motel because there was no space available.

The police arrested Sharpe at the nearby Pine View Lodge on a fugitive from justice warrant early Sunday morning, flushing him out of his room with pepper spray grenades thrown through his window.

County prosecutor Robert Weiner, the state's top lawyer on the case, said that he intends to seek an indictment from a grand jury sometime in August. A $100 million wrongful death suit has also been filed against Sharpe on behalf of his three children.
