Massachusetts Supreme Judicial Court August 14, 2018, SJC-12451 (Williams v. Steward Health Care Sys., LLC)

GAZIANO, J.

*1194On February 21, 2012, Mary L. Miller was fatally stabbed in her home by "N," her neighbor and a former patient of Steward Carney Hospital.4 In this appeal, we consider whether the hospital owed Miller and her family a duty of care and, if so, whether a breach of that duty occurred when one of its physicians released "N" from involuntary psychiatric commitment.
