(CNN) -- A Massachusetts grand jury has indicted a 98-year-old woman, accused of strangling her 100-year-old nursing-home roommate, on a second-degree murder charge. Prosecutors say Laura Lundquist killed centenarian Elizabeth Barrow, a resident of Brandon Woods Nursing Home in Dartmouth, after the two women had an argument over a table Lundquist had placed at the foot of Barrow's bed. Barrow was found dead September 24 with a plastic shopping bag tied loosely around her head, according the Bristol County district attorney's office. An autopsy indicated Barrow had been strangled. Barrow complained that the table obstructed her path to the bathroom, authorities said. When a nurse's aide moved it, Lundquist punched the aide and grumbled that her roommate "might as well have the whole room," prosecutors said.
