A comatose woman whose plight tested Connecticut's right-to-die law died Tuesday, just over a week after a feeding tube that was sustaining her was removed, the family attorney said. Carol McConnell, 57, of Ridgefield, Conn., died of pneumonia without waking from a coma induced by a car accident in January 1985, said attorney Stephen A. Wise. McConnell's family was at her side when she died at the North Stonington home of her daughter, Kathleen McConnell-Hewitt.
