Barbara Clark, the Pittsboro housekeeper accused of fatally beating her former employers, was charged with a second count of murder on Monday after another woman died over the weekend.

Clark, 41, was charged with the first count of murder last week after Mary Corcoran, 82, died Wednesday from injuries sustained during the beating. Margaret Murta, 92, died Saturday.

Clark is accused of attacking three women — former employers Corcoran and Murta, as well as Rebecca Fisher, 77 — in a Galloway Ridge apartment on December 5, after the women confronted her about stolen checks. Fisher was reported to be in stable condition at UNC Hospitals on Monday.
