Joyce Elizabeth Mangini was 74 when she died at Somerset Medical Center in Somerville, New Jersey on February 23, 2003. Her death was initially recorded as natural, but subsequent inquiry found she had been given a lethal dose of the heart medication digoxin while under hospital care.

The investigation at Somerset Medical Center identified nurse Charles Edmund Cullen as responsible. Cullen was arrested on December 12, 2003, and later confessed to killing dozens of patients, including Mangini. In April 2004 he pleaded guilty to the murder of 13 patients and the attempted murder of two others at Somerset Medical Center; in March 2006 he received 11 consecutive life terms.

Joyce Mangini’s death was one of several cases that exposed a pattern of patient killings at multiple facilities and prompted scrutiny of hospital oversight. If anyone knew Joyce or has information about her care in February 2003, please come forward.
