( 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 . District Attorney C. Samuel Sutter said Barrow repeatedly complained that Lundquist was making her life `` a living hell '' in the weeks leading up to the woman 's death , and that Lundquist remarked that she would outlive her roommate . A nursing home spokesman said the facility twice presented Barrow with the chance to change either rooms or roommates , but she declined each time . He compared the pair to `` sisters , '' saying they took `` daily walks together ... ate lunch together every day , and were heard at night saying , 'Good night , I love you , ' to each other . '' Lundquist 's attorney , Carl Levin , contends his client was not involved in Barrow 's death , saying , `` We maintain her innocence . '' A superior court judge granted a motion to send Lundquist to a state hospital for a competency evaluation . An arraignment will be held only if Lundquist is found competent to stand trial .
