Aggie Marsh, a 97-year-old white female, died on November 14, 1984, at the North Horizon Health Center in St. Petersburg, Florida. Her death was initially one of several that raised concerns among staff and investigators due to the sudden and suspicious nature of the fatalities occurring within a short time frame at the same facility.
Subsequent investigations revealed that Aggie Marsh had been murdered by Bobbie Sue Dudley Terrell, a 35-year-old registered nurse employed at the nursing
home. Terrell pleaded guilty in 1988 to second-degree murder charges for killing four elderly patients under her care, including Marsh. According to court records, Terrell strangled Aggie Marsh and another patient, Stella Bradham, an 85-year-old white female. Two additional victims, Leathy McKnight and Mary Rae Carter both white females, were injected with fatal doses of insulin. A fifth patient, Anna Larson, age 94, survived an insulin injection but later died of unrelated causes.
Terrell began working at North Horizon on October 2, 1984. Her crimes occurred over a span of days in mid-November, with Marsh's death marking the beginning of the tragic sequence. Witnesses described Terrell as emotionally distraught following the deaths, though she showed no emotion during her court appearance. The prosecution reduced the charges from first-degree to second-degree murder due to Terrell's documented mental health issues and the frailty of many witnesses.
In addition to the murder charges, Terrell pleaded guilty to attempted murder in the case of Anna Larson. She was sentenced to 65 years in prison for the murders and an additional 30 years for the attempted murder, with both sentences to be served concurrently. The case shocked the community and highlighted vulnerabilities in elder care facilities, prompting calls for stricter oversight and mental health evaluations for healthcare workers in sensitive roles.
